Which XTP load for Sig P210A?

My P210A slide is with Jon getting a full rail to accept an Aimpoint, will use a 9000SC or Patrol Pro. I've shot a bit of 115xt out of it but thinking the 124 or 147 may feel less snappy. What's your favorite XTP load for your P210A?

Oh, what a pity to put an ugly "coke bottle" (a 9000 - yes I know they are good - I just got one myself and Jon is working on something for me too) on the beautifully svelte P210A!

But, to address your question, I had very good results with 147JHP over 4.3 of Power Pistol, COAL 1.130. Crimp 0.375, which produced about 920fps. I tried both XTP and Zero JHP bullets - hard to tell the difference. For reference, in my iron sight gun with standard spring, etc., 4.5PP = 980fps, 4.7PP = 1,030fps.

But with a 9000 on the slide no doubt you will need more Ooomph!

I also tried Accurate #2. With same 147JHP bullets; 4.0 = 890fps from my gun.

YMMV!!!

May go with the Aimpoint Patrol Pro on it with a single large ring, saves a couple ounces. The 9000SC could go on my backup 45 wadgun. Was looking at the XTP 147 pretty hard. Need to find more PP, I'm about out.

Also to add, my CZ75 Accushadow is a superior 9mm irons pistol but the P210A is no slouch, just too light and snappy with stock irons. When the ruskies invade the CZ and custom AR will be at my side lol. This heavy P210A with full size dot will be a target queen.

Reminds me of that famous Abba song.

Target Queen, Target Queen. Dah, dee, da da dee, da da dee! Etc.

147 XTP w/3.4gr Alliant e^3 at 1.100" to 1.120". No crimp per se...just re-size top 0.1" of case. You may need to step up the charge a bit with the additional weight on the slide. Do a plunk test to see where the rifling on your pistol comes into contact. The Magnus and Zero 147 JHPs allow for longer bullet seating...the XTP does not.
