Just buy the 29, then you won't need any more excuses "not" to handload.
(unless you already do, then disregard this post)
This ^^^^^^^^^^^
I have a G20, G22, and G29. All in the SF model. Pearce extensions on the 10 rd G29 mags. No recoil problem in and load. The 29 is my favorite followed by the G22. And like said, it's a good reason to get into a reloader! Though, there are indeed many places now selling full power 10mm new ammo and more that sell reman ammo. 10mm is no longer the rare ammo it was due to the returned popularity of the round.
