    Again I am undecided Do I go for a new glock 22 or step up to the magnum power of the 10. I already own a first gen glock 21 in 45 acp which I love and can shoot like a bastard just looking for a new toy.

    Definitely the 10


    But I hope you reload, or you will need a second job to feed it.

    Find someone that has a 10mm that you can squeeze off a few rounds. A range might rent one. It's not for everyone. But those that like the really like them. I personally love the round. But it can be a bit snappy.

    If it were me...I would just get both!!! If it has to be one at a time, then I would start with the 10mm

    Yes, definitely handle both frames and shoot both calibers. I like the 10mm but if you want CCW the 40 makes more sense. Myself, I went with the G22 and G23.

    Go with the 10MM! You will never regret it! Plus you can just buy a conversion barrel for it like I did for mine, and shoot .40 when you wanna save money on ammo!

    I'd get the .40 and put in a 38 Super barrel if you want "magnum power".

    .38 Super would still not be able to reach the ballistics of a 10mm.

    I am going to get beat down for heresy, but...

    The .40 S&W does not differ that much, in terms of ballistics, from the 10mm.

    Here's some data from DoubleTap. I've jiggled it to line up the grain weights. The numbers at the end are inches of penetration and expansion

    .40 : 135gr. Nosler JHP @ 1375fps - 12.10" / .72"
    10mm : 135gr JHP @ 1600fps - 11.0" / .70" frag

    .40 : 155gr Gold Dot JHP @ 1275fps - 13.00" / .76"
    10mm : 155gr Gold Dot JHP @ 1475fps - 13.5" / .88"

    .40 : 165gr Gold Dot JHP @ 1200fps - 14.0" / .70"
    10mm : 165gr Gold Dot JHP @ 1400fps - 14.25" / 1.02"

    .40 : 180gr Gold Dot JHP @ 1100fps - 14.75" / .68"
    10mm : 180gr Gold Dot JHP @ 1300fps - 15.25" / .96"

    .40 : 200gr XTP @ 1050fps - 17.75" / .59"
    10mm : 200gr XTP @ 1250fps - 19.5" / .72"

    Given the newer powders like Titegroup, it's very possible to meet or exceed the 10mm in terms of FPS/penetration, but far be it from me to recommend exceeding SAMMI pressure envelopes :D.

    I'm quite content with the .40, myself.

    BTW, unless you're shooting 230gr rounds, the .45 underperforms both the .40 and the 10mm. However, ALL these calibers are perfectly suitable as defensive rounds, so this is really a "How many angels can fit on the head of a pin" kind of discussion.

    See? I told you I'd commit blasphemy :D

    .38S will deliver 540 ft-lbs of muzzle energy, nearly as good as the best .45ACP defense rounds. If that won't do the job, you need to rent a cannon.

    Or from Saint John's master creation, the .45 ACP.

    Another consideration is ammo availability, selection and cost.
