Awesome little pistol! Accurate shooter, great quality and fun to shoot! However it did have a tendency to jam now and then. Maybe didn’t like the ammo I used.

I am impressed as this is an excellent pistol for planking! used it to teach my wife how to handle a gun and then I purchased another one for me!

This was a beauty and fun to shoot.

This pistol was accurate right out of the box. Manual says to use CCI ammo which shoots fine. It did jam when I tried other ammo.

Its a sig ! Keep feeding this the right ammo and your are good to go. I did go through a few jambs but they are few between. I find this to be very accurate and like the sights it comes with. I know this sounds crazy but I wish I could fire shorts thru something like this - but if I could it would never cycle... it comes apart easy for cleaning. I like it... - buds is a great place to are in and if you are in Lexington you gotta visit the store. its amazing

I love the Mosquito. I have had several of these and they are just fun. Yeah they like good ammo but that’s not a problem if you buy in bulk.

Ordering is very easy and fast delivery.

Bought this took it to the range had nothing but FTA problem's.SOLD IT

Great target pistol. Only likes CCI ammo.

My was my first pistol several years ago. I still love to shoot it and do quite often now that .22lr is available again. Poor thing gathered dust during the shortage/hoarding years. Only ever had problems with bulk white-box ammo and the occasional dud with the higher dollar stuff. Great gun. Don't confuse the quality of this Sig with the Firefly clone.... I sometimes wish there was a truly reliable .22 round with a load hot enough to use for self-defense because of this gun. It's a great size and never had an issue with it. I look forward to teaching my nephew to shoot with it when get gets old enough. Bud's was great as usual.

Great gun, no FTF or FTE. I had heard some of these guns were having problems but this one functions flawlessly. Handled all ammo well. Accurate and fun to shoot. Great practice gun if you own a 226.

I bought the mosquito as it has similar operations to my P226. I hoped to use as a teaching tool. If you want a gun that miss-feeds, miss-fires, fails to clear the spent casing and is altogether a total failure this is it. It has been back to SIG twice but works no better. I was going to sell or get rid of but has turned out to be a great teaching tool - it exhibits every failure possible. I love me Sig P226 and would not trade it for anything. If you want a reliable .22 avoid the mosquito it has been nothing but a total disappointment.

Received this firearm 2 months ago and have since then put over 1,000 rounds through the Sig Mosquito. Many of the literature you read is somewhat correct - that it is slightly picky with the ammunition when breaking it in. I had the best experience with CCI Mini Mags - and they can be difficult to find. Lower grain .22LR sometimes had difficulty cycling in the gun which had to be manually cleared. Past the 500 round mark, it was a bit less picky. The firearm is well balanced and fairly accurate with some slight adjustment of the rear sight. The item, although purchased from Buds, was actually shipped from a completely different supplier - I thought FFL dealer had the wrong firearm. Despite that small confusion, I'd recommend the Sig Mosquito and Bud's - always a great deal.

Good gun, shoots great would buy again

took this sig to range today shot about 200 rounds used CCI mini mag, no problem at all great PISTOL. fast shipping from Bud's AAAAA +

I think this is one of the best 22 s out there

Took this sig mosquito to the range. Fired 150 rds of Federal 40 grn 22 lr bullets. Had 2 bullets that would not fit into the mag. HMM. To long. I never had this problem. Factory defect I guess. The mosquito shot point of aim consistantly. I put a sig laser on it and it was off (low) about 3in at 20 yards. I will correct this later.This gun had none of the problems i have been reading about. Jams, feed problems ect. I had 1 fail to fire. Tried it again, same bullet, did not fire. Checked the bullet, 2 hits but no fire. A bad round. This is a very light hand gun. It seems accurate, and reliable. for the money I recommend it especially for new shooters learning to shoot auto pistols. It is a well made pistol. bob

Very fast shipping from Bud's. Sig Mosquito is a great little gun.

To start with Bud's was great as always. The Sig Mosquito should be called the Sig Maybe, maybe it will work, maybe it won't. I never fired more the seven rounds without some type of failure. After filing and polishing the feed ramp and cleaning up the edges of the magazine it works great. But when I buy a new firearm from a company like Sig Sauer I expect it to work out of the box.

Great pistol. I've had the same obvious issues as everyone else, but I'm about 1000 rds into it now and Issues almost non existent. Buds was awesome as always!

There's a reason I'm only rating this 2 stars. It should say in the deception that if you want this sidearm to work, you can only use CCI mini mags. I sent it back to the manufacturer twice trying to get help with it. They sent it back both times saying it works fine with mini mags. If there was an option on what ammo was readily available, I'm sure this would be a nice sidearm. Ended up very disappointed with functionality.

Worked flawlessly out of the box. Very accurate. Very comfortable and ergonomic.

Great little gun, well made and looks good. One thing to note is that I've had SERIOUS loading and jamming problems since day 1. I've been trying to get through a box of 1000rds I picked up of Winchester Super X 40gr high velocity .22lr rounds, sometimes brass ejects only half way and I have to clear it, sometimes the new round refuses to load properly, sometimes the gun doesn't cycle at all. I have yet to buy and experiment with any new ammunition, but I was hoping that buying a Sig and using 'high quality, high velocity' ammunition would work well, and the fact that it does not is very disappointing. It's not that fun to shoot when there are 2-3 misfires out of EVERY magazine I shoot. My belief is that the ammunition I'm using does not pack enough punch to get the slide to kick all the way back every shot and this causes the loading problems. I have cleaned and lubricated it well and have still had problems. Next step is trying different ammunition, if that doesn't work then take the thing to a gunsmith and see if there's some machining to be done to get it to fire properly. Other than that I love the gun, but you should be aware before you buy that there are some issues you're likely going to have to deal with to get it to function the way you expect it to!! Quality of the gun itself is 2nd to none, I would rate it 5 stars except for the jamming, but the gun is so sexy and easy to use I'm still rating it highly.

Almost everything about this handgun is excellent. Excellent sights and it even comes with a spare set. Great accuracy, but lacks in precision (but that's what you get with a .22LR handgun). It's a full-sized handgun and the grip feels great in your hands. And the most important positive thing about this gun is that it is really cheap to shoot. I find myself shooting this gun more because of how cheap it is. The only negative thoughts on this gun are that it only comes with one magazine and these magazines are not cheap (at least $40 each for a 10rd.). And lastly the use of lead nosed ammunition will cause a lot of failure to feed problems. When I run copper nosed ammunition through the handgun it shoots flawlessly, and it doesn't matter what kind you run. I ran cheap lead nosed ammunition to the expensive CCI and Federal lead nosed ammunition and I was getting failure to feed every other shot. However, when I ran cheap (and very dirty) Remington bulk HP copper nosed ammunition to even the expensive CCI Mini-Mag round copper nosed ammunition it still shot flawlessly. The reason for this is because of the steep ramp that the bullet has to ride up. Lead nosed ammunition is not as smooth as copper nosed ammunition so the lead nosed always get caught on the ramp. One way I've heard to counter this problem is to polish down the ramp or otherwise let nature take its course and shoot a lot to break in the gun. I've heard that some owners shot almost 10,000 rounds to fix the failure to feed problem. I'm taking latter step because its more fun.
