    Balances quite well in the hand. I like the longer grip with the shorter slide, it's a perfect balance. Got this because I liked the 19X so well.

    I recently purchased this firearm thank you Westcost Security, and I have to say it is perfection. The size makes it really easy to conceal in the grip makes it so much easier to control the recoil. I would definitely recommend this to anybody who is a first time shooter and wants to do it all carry gun. Best Glock on the market

    THIS IS WHAT I WANTED!!! Just decided to add one with her sister plus I’ve been needing this COA. The best Glock in my opinion due to it checking every need and want on my checklist and then some. Keeping her stock other than changing out the sights for some TruGlo TFX Pros

    I just received it, thank you sir! Getting ready to issue these to my department. They shoot amazing and I can’t wait to see the smiles on everyone’s face. This is definitely my new favorite Glock and I have been shooting them for 20 years!

    Love this Glock I bought this Glock after I bought my 43X. I wanted a full size pistol with more magazine capacity. 17 + 1 was definitely the way to go. Shot this gun and the recoil is very soft in comparison to my 43X and the even though everyone hates the Glock sites this was a very accurate gun. No adjustments. I have to shoot a little right on my 43X. Great gun, feels good in hand and it has softer recoil. Love it.

    My Process It was the easiest process to do a background check. And my salesperson had great knowledge of the gun I bought and was telling me stuff I didn’t know.

    Best combination between barrel length and magazine capacity (grip length), that means more control. Glock Gen5 technology so simplicity and reliability is in all components. 1000 rouns through it in two days with cero mal function. No doubts just the best.

    Westcost Security should let you field strip the gun before purchase My slide was stuck on the G45 COA I had to get it worked on. Also, there is supposed to be four beaver tail extensions in the box and there were only two.

    First firearm I have ever purchased. I purchased for concealed carry and it hides rather well regardless of the 17 rd capacity. Very accurate and handles well. Put 200+ rounds right out of the box with no issues. Compatible with Glock 17-17 rd mag and Glock 19 holsters. Great buy and it came with 3 mags.

    I like this one better than any other Glock model ever made. I get a much better grip on the full sized handle than I do on a g19, and yet I still get the instant sight alignment that I do with the g19. I really like all the gen 5 features - front serrations, beveled front of slide, ambi slide stop, no finger grooves, but best of all the trigger which I think is the best stock glock trigger to date. I was able to purchase this online through Westcost Security when I couldn't find it elsewhere, and the price was lower than most other places.
