    So, it's been a long road, but I'm finally here. :)

    I'll spare you folks most of the details but I was originally looking at a Beretta PX4 Storm in either .40 or .45. Doing research informed me to the 10mm, the parent of the .40. Lo and behold, Glock has a 10mm (one of the few and extremely highly rated) in both fullsize and subcompact.

    The problem I'm running into is deciding which one, the 20 or 29 and the sf or normal ones.

    According to Glock's website, there are 6 choices.

    Glock 20
    Glock 20 Gen 4
    Glock 20 SF
    Glock 29
    Glock 29 Gen 4
    Glock 29 SF

    I'm just confused - are the SF versions not Gen 4 versions? Is there any reason I'd want a Gen 4 over a non-Gen 4 version? I used to own an HK45 and was extremely comfortable shooting it - how does it compare size-wise to the Glock 20?

    I think I've decided on the Glock 29 (this will be my first Glock), just... not sure what all it means. Thanks!
     
  2. Go with the gen4, I have a gen4 20 comparing the felt recoil to the gen3 I had, the gen4 recoil feels less, plus you have the option of changing the backstraps for a better fit.:supergrin:

    I think you will really appreciate the grip texture of the Gen4 G29 (10+1). It helps hold it more securely when shooting the hottest 10mm ammo, especially if the grip is wet or you're wearing gloves.

    The Gen4 frame has a different, more aggressive grip texture (RTF3) around the entire circumference of the grip and a larger mag release button that is easier to reach. The mag release is reversible for left hand shooters. Gen4 comes with two backstrap adapters to increase the grip dimension front-to-back (2mm & 4mm). Without a backstrap adapter installed, the Gen4 is essentially the same dimensions as the Gen3 G29SF (Short Frame). With the 2mm backstrap adapter installed it will be the size of the Gen3 G29 (Standard Frame).

    The Gen4 G29 comes from the factory equipped with the "•" connector and includes three, 10-rnd magazines (one more than Gen3).

    The Gen4 G20 10mm (15+1) incorporates a dual recoil spring in that pistol for the first time. The Gen3 G29 and G29SF 10mm subcompact pistols already have the dual recoil spring and that did not change for the Gen4 G29 model recently released.

    Outstanding - thank you!

    So, equipping the "small" backstrap on the 20 or 29 Gen 4 is the same as having it in the SF size. Excellent.

    This is the first I've heard of this - what is the "." connector?

    Thank you as well, G36. :) I feel kinda like an apostate coming to Glock after owning an HK. ;) It was honestly the drop in Lone Wolf barrels that sold me on the 29 - for a few hundred more, I could have 4 guns in one (10mm, .40, .357 and 9x25).

    Close, the Gen4 (20 or 29) without any backstrap adapter installed, as it ships from the factory, is Gen3 SF size. There isn't a small adapter, just a medium (2mm) and large (4mm) adapter.

    This link will tell you all about the origin and purpose of the Gen4 "dot" connector: http://militarytimes.com/blogs/gear...-introduces-the-connector-5-for-gen4-pistols/

    Outstanding GRT45, thank you!

    It sounds like the Gen4 G29 is in my near future. :)
     
  7. I was thinking about a 29 myself. I was surprized of the velocities posted in a gun test in March Shooting Times magazine using DTs 180grn. I thought it would be a little faster than 1100fps. I'm not sure what other ammo runs but I thought DT ammo was suposed to be hot.

    It may be different now, but in the past DoubleTap had a reputation for over-promising and under-performing with their ammo. In contrast, Underwood Ammo has a reputation for performance equal to the claims on the box.

    GT member icelandicstud made some videos with chrono data that were very helpful to me. He posted the videos here: Range Trip - Glock 29 20 & longslide 10mm stuff. I have summarized some of his results below:

    Underwood 10mm 180gr Gold Dot JHP

    G29 with 3.78" Storm Lake barrel: 1262 fps avg
    G29 with 3.78" Glock OEM barrel: 1231 fps avg
    G20 with 4.60" Lone Wolf barrel: 1346 fps avg

    Underwood 10mm 165gr Gold Dot JHP

    G29 with 3.78" Storm Lake barrel: 1362 fps avg
    G29 with 3.78" Glock OEM barrel: 1308 fps avg
    G20 with 4.60" Lone Wolf barrel: 1409 fps avg

    Underwood 10mm 135gr Gold Dot JHP

    G29 with 3.78" Storm Lake barrel: 1524 fps avg
    G29 with 3.78" Glock OEM barrel: 1499 fps avg
    G20 with 4.60" Lone Wolf barrel: 1630 fps avg
