I have a lot of Glocks. Love'em. I have a lot of experience with them. Not as much as some, more than others. The first Glock I shot was a 26. I had been shooting a Smith 5906 (a lot) and the differences in the pistol were great so I didn't pay it any mind. I had small children at the time and liked the external safety and DA/SA of the Smith even more just for this reason. I wouldn't shoot a Glock for another 11 or so years, after I retired from my first agency.
When I became a State Criminal Investigator I was issued a Glock, a 23 in .40 S&W. I was immediately informed that I was not allowed to carry it off duty let alone shoot it away from a State sanctioned range without a State rangemaster watching everything I did, thought, spoke or breathed. So I bought my first Glock, a 23 in .40 S&W (screw you Colorado
). I could carry this off duty. Doing so meant it was time to practice Glocking around. This led me to picking up my 27, the sub-compact little brother to the 23 and allowed to be carried as a BUG on duty. I think I shoot the 27 better than I shoot the 23. The 23/27 combo, backed up with either an AR-40 or AR-15, was my carry for the next 11-12 years(?).
So. Here is my .02¢ on buying a Glock if you are so inclined. If you have small hands you may want to start out by trying the Glock 42, their .380 model. I have not owned or shot a 42. A friend had one and it is smaller. Definitely smaller. Like, if I feed it and nurture it, it might grow up into a real gun one day small.
I have owned and shot a 43. I did not own it long. I sold it when I picked up an MOS model of the 43x. The grip is slimmer. Slimmer still with the 43, 43x and 48 have the same frame. It wasn't that I didn't like the 43 but it was that it irked me that they wouldn't share mags. WTF? Really? One of the great things about buying Glocks was that you could basically plug a larger mag (of the same caliber) into your smaller one and keep on Glocking. I did end up with a non-MOS 43x later but that was only because I was at a craft fair.
Moving up is the sub-compacts. I own a 26 and a 27. The 26 was basically a steal. The officer selling it just wanted to get rid of it and I will buy a gun if the price is right, even if normally I wouldn't go near it. This actually explains why I have a robins egg blue (teal?) Ruger Security 9 Compact.
These are great. They conceal well. There is a ton of aftermarket support for them. They take the mags of the two bigger sizes in their separate calibers (and more). Before I got my 26 I actually picked up a 9mm conversion barrel for both my 23 and 27 so there is that as well. But these are a little chunky. Medium sized hands or larger is what you need. This is true when moving up in all of the Glock sizes actually.
There are large frame Glocks as well. Their .45 ACP and 10mm models. I am not Glocky enough to tell you all of the models and versions but can say that I own a LE trade-in Glock 21 (.45 ACP). I also have a 10mm conversion barrel, RSA and mags to shoot 10mm out of my Glock 21. I feel like I have large medium hands or small large hands. I can't palm a basketball by any stretch. I would not recommend either of these as a first purchase unless you had big hands or had to have either a .45 or a 10mm.
I'm pretty sure that this does not answer your question...
), which one would the guys recommend for me? I figured I would throw a thread up here and, if nothing else, become educated and entertained at the same time.
