as far as the 3.8 compact, yes. i bought a 3.8 and a 5.25 the same day. the only thing different with the 3.8 compact, is that it only has 2 mags. one 13 rnd, and one 19 rnd for the "sleeve" to fit over to make it a full size grip. (the full size mag still works without the "sleeve", just a bit tingly like a baseball hit improperly,) i don't know if the full size grip/frame of the 3.8 has the 3 mags like the 5.25. talk to your dealer.
honestly, i like my 3.8 better than the 5.25. to me, it seems to recoil less. i know, the bigger 5.25 "weighs more" and should "adsorb" the recoil better, but to me, with less reciprocating mass of the smaller slide of the 3.8, i think it shoots better. not as accurate because of the shorter sight radius, but better recoil management.
