Bought this as my first (build a glock) I replaced the barrel with a blacklist industries.. actually made a few different upgrades but I won’t get into all that.. I always run my guns as is when I first purchase them and honestly it was great without the upgrade I just chose to personalize it. Anywho I love the gen 4 grip texture and the rest is dependability

For a used Glock, this was an awesome purchase. Great price. I would recommend Buds used guns to those looking for a reliable gun at fantastic pricing.

The Glock 21 is a Glock....it is easy to maintain, easy to handle and always goes bang. Shipping was very prompt, as it always is when I buy from Bud's. What's not to like?

Perfect condition, works like a charm. Have to be careful not to limp-wrist with cheap ammo or one can get a stovepipe. Shipped promptly to my neighborhood FFL, everything went smoothly.

I've carried Glocks on duty almost exclusively for the past 30 years. Their quality is equal to or better than the other gun manufacturers and this Model 21 is no different. My hands are a little bigger than average so the double stack fits nicely, even with the larger back strap on it. It's far more accurate than I am and handles recoil nicely, even for younger/smaller shooters. Bud's shipping and service is top notch as well, definitely prefer to do business with them over 99% of my local gun stores.

I'm absolutely in love with this Gen 4 Glock 21. The power behind it is just enough to give you that Gun lovers tingle but the recoil isn't so crazy that you need another hand to absorb the shot lol

Like all Glocks, this is well made and well engineered. Shot perfectly right out of the box. However, I think this monster is just too big for most people with average to smaller hands, even with all of the grip inserts removed. The ergonomics are such that I found my trigger finger rubbing against the bottom of the trigger guard, a problem that I do not have with my Glock 19. If you are keen to get a 45acp, there are lots of better choices, like the good old 1911, which causes me no problems.

By far my favorite Glock. Shoots like a dream. Solid .45
