Why? Isn't the best reason to go with GAP the fact that it fits 9/40 frames? The M&P45 grip is barely bigger than its 9/40 siblings.watsoncb said:I would jump on a MP compact 45GAP in a second. Load with with Federal's low recoil 45GAP hydra shok rounds and the perfect CCW is born.
Dan Burwell said:I just don't care for the 357 sig round too much muzzle blast and noise for all the more power, plus I like the saying a .355 bullet may expand but a .40/.45 will never shrink.
You should have added to the poll: waiting for the M&P .45
MNPvsG said:357 Sig sucks
-Expensive ammo (usually less trigger time).
-No better terminal performance than a 9mm.
Excessive velocity of a 9mm (ie, 357 Sig) causes the petals of the hollow point to fold out (as a good 9mm does) but then over (decreasing permenant wound channel).
-More recoil impulse = slower follow up shots.
Plus it causes some shooters to shoot worse who anticipate the recoil.
The .357 Sig is not a bad cartridge, it just does not seem to offer anything that is not already available, at the price of less ammunition capacity than the similarly performing 9mm, as well as having greater recoil, muzzle flash, and wear on the weapon compared to other service pistol cartridges.
When firing through heavy clothing, automotive steel panels, automobile windshield glass, interior wall segments, exterior wall segments, and plywood, both the .357 Sig Speer 125 gr JHP Gold Dot and 9mm Speer 124 gr +P JHP Gold Dot exhibited nearly identical penetration and expansion results THROUGH ALL THE DIFFERENT BARRIERS, as demonstrated by both our testing and that of the FBI. Several .40 S&W and .45 ACP loads offered superior terminal performance through barriers compared to the 9mm and .357 Sig loads. With FMJ, terminal ballistics are identical between 9 mm and .357 Sig--you get all of the downsides and no benefit with .357 Sig FMJ.
Please note Doug Carr's gel test comparison of service pistol calibers below, along with some recovered projectiles from our testing:
Read: Roberts G & Lazzarini D. “Preliminary Evaluation of .357 Sig Jacketed Hollow Point Bullets Intended for Law Enforcement Duty Using 10% Ordnance Gelatin as a Tissue Simulant.” Wound Ballistics Review. 4(4):32-33, Fall 2000
The .357 Sig has nearly identical expansion and permanent crush cavity compared with the 9 mm, not .40 S&W or .45 ACP. As you can see above, the only area where the .357 Sig is similar to .45 ACP is with the temporary cavity, however, since the stretch effects are relatively minor with all the service pistol calibers and cause no significant injury, the similarity is moot.

We can all copy and paste ballistics reports until we go crazy. There are just as many reports from experts that validate that the 357Sig has better terminal performance. BUT, I think we are splitting hairs here. There is really very little terminal difference b/t the major service calibers. One thing is for sure, the 357Sig has an outstanding street record.
