I am planning to set up an M&P possibly 2.0 for my 105lb 13yo son and I have a few questions.
I want to load up as light a load as possible for him to start. I am not worried about keeping the gun or load production legal. I plan to install an Apex trigger and barrel and run a 13lb recoil spring.
How low of a pf will likely run the gun? I am currently using AA#2 powder and 115 or 124 jacketed bullets.
Is it true that the 1.0s will run low pfs better than the 2.0s?
Would you suggest a 4", 4.25, or 5 inch gun?
Will the 4.25 or 5 inch slides work on a 2.0 compact frame?
