I am not a Glock Fan. Just don't like the appearance, and feel. My GirlFriend is a State Arson Detective. When she was going through the Police Academy, I gave her a four inch model 19 S&W. Wish I hadn't but I did. I miss that gun. I have a six inch 19, but really liked the four inch one also. Anywho, she really wanted an automatic, cause that was what most of the other detectives carried. She really liked the Glock. Ok. I went to the gun show, and found a really nice Glock model 19 in 9mm, with after market sights. I didn't care for the feel or the look of it. It shot fine, just not comfortable with it. So I gave it to her. A month later they issue her a Sig 228.
She also has an Astra A70L in 9mm which she really loves. She always qualifies well with it. I like it also, I had to buy her one, since I made the mistake of showing it to her, and letting her shoot it. It is double action auto, so you can carry a round in it, with the hammer down. She doesn't like the 1911 because it is not double action. I tried to explain it to her that I can cock it on the draw, and not be any slower than a double action. Anyway, she has a lot of my guns now. She bought a .45 Glock compact, which she really likes, and then they issued her a .40 cal Glock.
I have a Friend who has one and loves it. I have shot it and it shoots very well. Just don't like the look and feel. I will take the 1911. I have a few.
I have the little Ruger lcp in .380, it is double action only. It has a loooong trigger pull. Once you get used to that it shoots pretty well for a pocket gun, and like the Astra, you don't have to worry about shooting your identifying items of sex off. I just have never been a Glock Fan. Oh, and the Fobus holsters are crap also. She has gone through three of them. The little rivets they use to assemble it, are too small, and need a washer under them. Kydex holsters can be twisted off, by an attacker. It is not difficult. There is a You Tube video on that. There should be after market parts for your Glock in the Brownells catalog. I don't know if there is an after market trigger for the Glock since that is your safety. You can Google them, and go on their e-catalog, and look them up. I have some little pocket pistols, like an Astra .25, the same model of the colt. In fact Astra made the little pocket Colt, for Colt. I also have a little Italian Galesi in .25 also. Never carried either of them with one in the chamber. Juuuuuust don't trust them that close the jewelry box.
When I do Carry it is usually a .45, 9mm, .380, or at least a little .32 derringer. I consider it a distractant, so I can get to another local.
A lot of people love the Glock, I don't. Just my personal opinion. As for Police officers shooting themselves, I had a H&K P7 with the squeeze grip safety. The NJ PD bought them, and a little while later turned them all in and bought I think S&W's. Seems too many officers were either shooting themselves, or discharging when not ready. It takes a little getting used to, but a nice little gun. I sold mine to a Friend's Son, who just had to have it. Like I said check out Brownells, they should be able to help you or point you in the right direction. Be careful you don't void the warranty by changing parts.
You either like Glocks, or you don't .
If you like em, enjoy!
