GLOCK 21 SF (Short Frame)

The “big bore” 45 Auto caliber has since long been regarded with a special reverence. Many shooters feel a special relationship with this timeless caliber. The GLOCK 21SF presents everything one would expect of a 45 Auto pistol. The SF design reduces the circumference of the receiver, offering increased ease-of-use and control, especially to shooters with smaller hands.

Used Glock 21 SF Police Trade In.

Shipped quickly and arrived at my FFL in 3 days.
Gun is in great shape. My only disappointment is that according to the listing and showing only 2 mags, I was under the assumption it was a Gen 3. The unit I received is a Gen 4. Gen 4's come with 3 mags from factory but this one only came with 2.
I was really hoping for a gen 3.
Next time I'll call to get confirmation first.
Irregardless of this, I'll buy from Gunprime again and I highly recommend.

Not Bad

What really impressed my about my first purchase from Gun Prime was their shipping speed. They shipped the day after I ordered, and it was at my FFL a couple of days later.

I have not shot my new pistol yet, but it appears in very good condition. I expect some holster wear on the slide, and that is what I found. When I tested the included magazines, they did not drop free empty when the mag release was pressed. I tried other G21 surplus mags that i had on hand (and appeared less worn) and they did drop free empty when the mag release was pressed.

At this point, I am very satisfied with my purchase.

Great buy!

I’m glad I “took the chance”! The 21 showed up and as advertised was in excellent shape! I broke it down for a quick peek and then out back for a function test! Very pleased! All was as advertised! Nice piece!!!

Good buy

Received this very quickly. Good service from Gunprime! Mine is a Gen 3 21 SF. It is very accurate, and went through 100 rounds without any problem. My only complaint is with the trigger. Even for a Glock, the trigger is very heavy and creepy, and caused me to drop a couple of shots low left. Oddly enough, it did not seem to bother me as much during rapid fire. Overall, a very good buy.
