Customer Reviews for Glock G21SF 13+1 45ACP 4.91" Threaded Barrel

It's a glock and it works like a glock. Nuf' said. Good gun.

Very big. Not what I expected. I have big hands and still don't like it very much. This is one you want to try before you buy.

First time bought a firearm online, it was a positive experience, very smooth process. Thank you !
This is my 2nd Glock, out of the box shoots tight groups . Zero malfunctions in the past three years, only shooting brand name ammo though.
Kinda big for everyday carry but i'm doing it anyway .Great fit and finish, great gun overall

The best.45’s Full Size on the market. The absolute best send me autos on the market no matter what caliber is yours go with go ou The absolute best semiautomatics on market no matter what caliber is yours go with Glock And don’t change anything and it don’t put any “upgrades quote and it leave it just like it is and it’s the best pistols on the market

The shipping was surprisingly fast. The firearm works well. The inclusion of the threaded barrel was quite convenient and saved me the money of purchasing a separate barrel. The grip is comfortable for someone like myself who has small hands (for a guy), although I bet someone with larger hands would still be able to handle it just fine. I will look into having a gun smith wack down the handle to accept Glock 30 mags, but that is due to conceal carry purposes and not any problems with the grip.

This is my 4th Glock and my 5th purchase from Buds and I couldn't be happier. The suppressor sights are very nice although the rear sight is just plain black, the front sight has a nice noticeable green dot. The thread protector that Glock gives you is junk. It's just a piece of plastic that just slides over the threads. I lost it while shooting it for the first time a few days ago. I haven't contacted Glock to see if they make some sort of replacement or what. Another thing I would like to add is the size of this glock. While it's comfortable in my hands, this thing is huge. My first Glock was a full size gen4 17 and this one is way bigger than my old 17. This Glock is fantastic and shoots great.

Finally got my G21SF/TB to the range. Smooth as silk to shoot. I put about 100 rounds of my reloads of FMJ and JHP through the pistol with no problems. I added Trijicon suppressor night sights , extended slide stop , extended slide lock and a full metal recoil spring. A great addition to my small Glock collection which incudes the G30S. I have also purchased a 10mm conversion barrel and G20 15 round magazines that I will review later.Very highly recommended !

My 2nd purchase from Buds thanks guys. Glock quality, already changed slide stop release. Threaded Glock barrel is M16 x 1LH also has suppressor sights (non night sight). mine only came with 2 mags. Also purchased AAC piston for suppressor thru Buds fast shipping on both. Thanks again guys.
