5 of 5 THIS IS IT!!! May 5, 2024
Reviewer: Anthony Salkauski from Hamilton, NJ United States  
First of all I Love my M&P40 Shield! I just picked up my second one, had the 3.1” and added the 4”. Get the Maggutts +1 spring to rock that 8+1 and most importantly get the TR-Enabling Extended and Ported 357 Sig conversion barrel. 357 Sig with a 4.25” barrel will net you 600 lbs of energy with certain Underwood loads. When you get around to it, put that optic on a range toy and replace it with a Holosun 407K, 507K, or their new EPS MRS optic and you will have a ultra concealable beast with 357 magnum energy that is sure to get you through any ordeal. I have thousands of rounds through these barrels and they are superb!
