I am new to this forum and this is my first post. I am a retired LEO and carried various Smith j frames for years as backups(36, 60, 38, 49, 642). Since retirement I have carried my off duty gun, a Colt 1911, daily for the last 11 years giving my last j frame to one of my daughters. I recently started experiencing back and hip pain(sciatica)that has prevented me from carrying any handgun on or in my belt. I just purchased a Smith M&P 340 and have put 100 rounds through it so far. Being very familiar with the platform I found the gun easy to shoot with several different .38 loads but I wanted to try .357. Bought a couple of boxes of the Remington Golden Saber 125's and loaded her up. I didn't know what to expect but I was pleasantly surprised. The recoil was stout but manageable. All five shots, slow aimed fire, were in the 10 ring at 7 yards. The second cylinder was fired as fast as I could acquire a sight picture and squeeze the trigger. All five were center mass and inside the 9 ring. Remainder of the first box was the same. I know the Remington round is considered a mid range .357 but it still appears to be better than a 125 +p .38. I will next try a low light shoot to check for excessive muzzle flash. I have small hands and short fingers so the factory grips are fine for me. I will be carrying in right front pocket with one of several leftover holsters but haven't decided which yet. Do those of you who carry and shoot .357's in yours have other suggestions on loads to try?
