I recently rented the regular frame Glock 20 at my local range and shot really well with it and really enjoyed it. Thus, now I MUST have one. However, the grip did feel a bit bulky to me, especially the "hump" at the bottom, which is the reason I believe it points high for me. Some time ago, I had a Glock 21SF, which I sold shortly after acquiring (got an offer I couldn't refuse). The thing that stands out most about that pistol is how comfortable I found the short frame grip (didn't shoot it much). So, I am torn between the regular frame and short frame Glock 20. There are no short frame glocks available to rent locally, so I cannot do a side by side comparison. Honestly, I shot so well with the regular frame that I am hesitant to get the SF despite how comfortable I remember the grip being. From my experience, just because a gun is comfortable doesn't mean you will shoot it well and vice-versa. For example, the HK P30 is very comfortable to me, but I shoot the Beretta 92fs much better even though it is not as comfortable. Do you think that since I shoot the regular frame well, I should just stick with that, even though I really do find the short frame much more comfortable? Is it conceivable that I might not shoot the SF as well due to the different grip? Do those of you that have shot both find that you improve with the SF or Gen 4 grips? Thanks!
