    Hey folks, new to handguns here. I recently inherited a .25 cal handgun. In the process of deciding whether to keep it or sell it, I wound up trading it for a Kel Tec P11. Now I am looking at Glocks, but I am not sure yet which way to go. I know that it is cheaper to shoot 9mm ammo, and there is the benefit of only buying one type of ammo, but here's a few questions. First, if I were to buy a Glock 17 Gen4, should I get one stock, or with a compensated barrel? I had a Pawn shop guy offer to sell me a Gen4 .40 cal yesterday for $100 off new. He sold the gun 2 weeks ago new to the owner, but the guy needed cash. I just don't want to spend the $$ on the ammo. His advice is that it has more punch than a 9mm, but I am carrying Critical Defense rounds in my P11. If I go with a bigger round, I would prefer to go with a Glock 21 Gen4 and shoot .45acp.

    This leads to question number two. Should I go with a 17, or 21? I see good reasons for both. If I go with the 17, I need only to buy 9mm ammo, it is plentiful and not too expensive for practice rounds. Or, would I be better off to go with the 21, and have the bigger round with more stopping power? I have always been pretty accurate with a .45, so this looks pretty good too! To wrap this up, I will probably keep the P11 for CC since it is so small, but how hard is it to carry a full sized Glock? I did handle a 19 Gen4 yesterday, It felt awkward in my hand.

    Thanks for you help!

    If you want something different just for the sake of having something different, or if you want something larger than 9mm (for whatever reason) get the 21. Otherwise, common sense says buy a 17. Cheaper ammo, more money for magazines/training, faster splits, higher magazine capacity, commonality of caliber with your other... you get the picture.

    Personally, I have no place for .40S&W. To me, it solves problems that I don't have. If I were a LEO, I may feel different with the benefit of better medium barrier penetration, but I'm not, so I CCW a Gen4 17 AIWB.

    And IMO, the compensated models are unnecessary in 9mm and 45acp. It would be more beneficial in higher pressure cartridges such as .40S&W and .357sig if you must have one.

    The best part is, you can, and may vary well, purchase one of each eventually.

    Totally agree! Just bought one and changed out the sights and trigger! It is my favorite Glock.

    If we are talking strictly Gen 4s here, the 21 has my vote... by far.

    17. I save the 45acp for 1911's, Sig's, or HK's...

    It's pretty nice
    I've got a 21 and 22, both G4's. Both are great; reliable and accurate. For carry I'd choose the thinner, higher capacity 22 over the 21. For range if $ is'nt a consideration, either. If you want a high capacity Glock with the biggest bore, the choice is simple. The G4 20 and 21 seem much smaller in the grip than non-SF G3's, about perfect. The 9mm and 40 G4's (especially FS models) feel small around the grip, almost too small for me but just fine without extra backstrap installed.

    if i could only go one id go 17. 9mm is cheaper and easier to shoot/learn on for most people.
