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.

Great gun, but play with ammunition to see what yours likes. All the reviews that say they are finicky with ammunition are correct. Mine loves CCI 40g minimags. I have another friend that insist Remington Thunderbolt is the best. I think the key is keeping this gun clean and make sure you have the slightly more powerful .22lr rounds for it. It most definitely will function better. All in all, not my favorite Sig product, but still great value for the price.
