This is my favorite carry gun. It becomes almost invisible after a very short time wearing it in an IWB crossbreed holster. Very comfortable. Very accurate once you get used to it in the 40 cal round. Never an issue with operation. Can also be carried as

love this gun. it's small size is what sets it apart, along with the fact that its a glock. 40 cal is a great all around round if you like shooting a bigger bullet than 9 mm than u will eat it up at the range. a c c u r a t e

I've carried my Glock 27 for six years, it's easy to conceal, has enough power for any situation and it's extremely reliable. Never in over 1000 rounds of different ammo has it failed to feed. I bet my life on it every time I leave home.

With the exceptons of the sight and the slide lock release I really like my new pistol. This is my first large pistol and I have found it to be very plesant to shoot with some 158 gr ammo. I bought it to carry for trail protection and it seems to be very

I remember when I purchased this great gun, I couldn`t decide between buying a .460 s w custom short barrelled revolver, or this fairly potent(as far as semi-auto pistols go) Glock 4thGen. 10mm. Thank goodness I made the right choice and bought them BOTH

Got this for home defense/hunting side arm and it's perfect. Put a few rounds through it just because I couldn't wait to get to the range this weekend and it's accurate right out of the box. As always, bud's was fast and easy to deal with

Great service. I choose this pistol to have while camping in large bear and cougar territory. So far at the range it's a glock. No problems using defense and hot loads. Having this makes me feel more comfortable for my trip.

I bought the Glock 20 Gen 4 online and it was shipped to the FLL in a few days. All easy and good. I did rent one before actually making the purchase to be sure I was making the right purchase. I just got home from picking it up and shooting it 200 rounds

Let me start by saying this is my third glock and my third from Bud's. This gun is absolutely incredible. While it is the same size as the glock 21 after firing it you can tell this is no glock 21. This handcannon is ridiculously reliable, very accurate,

I've had this pistol for going on 2 years now, it was my second Bud's order. Everything went smoothly from the layaway payments to shipping to my FFL. And the gun...oh yes, that. The Glock 20 has long held a near-mythic reputation as a hand cannon, and th

Bud's did a great job as always. This is my first Gen4 Glock and I love it. It fits my hand better than my Gen2 and Gen3. Light. Easy to control. Goes bang when it's supposed to.

This firearm exceeded my expectations. PERFECT finish and fit (as it is a Glock), the Gen4's have a slightly thinner grip than the Gen3 models. This gun ALSO came with multiple beavertail addons BESIDES the regular Gen4 backstraps. 100 rounds and flawless
