Ever try the 10mm?
For example, the Glock 20...same size frame as Glock 21 in .45 acp, yet much less recoil, does not climb, gun pushes slightly back into your hand..with the right ammo, equivalency of a .41 magnum, very fast repeat shots.
Or get a hotter load like the Double Tap 230 grain hard cast, little more climbing than like .45acp!
Downside 10mm ammo is more expensive, less available. ;(
Kind of the reason I went with the 9mm Glock 17. I practice a lot, built my own target range on some property I own in the middle of nowhere.
The primary reason I went to a semi-auto was a little arthritis starting up in my right hand, particularly thumb. Always used single and double action revolvers before. The .44 Redhawk is no longer fun to target practice with.
Liked the Glock more than I thought I would.
