I love my G32 357SIG with 4.5" barrel... ...but I guess I have an itch... I've had a model 20SF 10mm, and while it surely had the power I'm dreaming about, I never loved the feel of the pistol in my hands, which are rather normal sized. I thought about a .40 Super or a .400 CorBon in a 21SF, but I kept coming back to the slightly-too-large grip of the 20- and 21SFs. THEN, since I love the 357SIG so much, I thought about the 9X25 Dillon in a 20SF. THERE, I thought, was the right combination of bullet diameter and overall power--but then I remembered that grip size and also realized that all that powder and cartridge length adds just about a hundred* FPS to the velocity--c. 1400FPS with 124XTPs--I'm getting from my 357S. So...this week I'll be trying Barnes solid-copper TAC-XP... http://www.barnesbullets.com/products/mle-tactical-bullets/mle-tac-xp-pistol-bullets/ ...125s in my reloads. Maybe they will satisfy that itch. * What else it adds is more recoil, more physical muzzleblast, and more noise!
