I've decided to hold off on a 10mm for now and decided to use what I have for trail use. I've chosen to use my XDm 4.5 with 357sig Storm Lake barrel.
I have a few boxes of Underwood 357sig loaded with 125gr Gold Dots and pushed to an advertised 1475 FPS. After some google-fu, it appears that this load from a 4.5"-5" barrel routinely makes it to and beyond 1550 FPS. That's around 670 ft/lbs.
17 rounds at the ready of such ammunition sounds decent enough for the mountains of WNC. If not, I plan on toting 2 additional 16-round magazines to repel ne'er-do-wells and large furry/toothy things with claws.
Being I plan on putting a few of these down range, maybe 250 rounds or more to test function, I figured a heaver-than-stock spring would be a good idea. I purchased both a 20 and 22 pound spring to replace the stock 18 pound spring while using Underwood or Buffalo Bore ammunition. In the past, I've only used stock springs with Underwood (with perfect results).
Presuming reliability is still positive with the heavier spring, is there any caveat using heavier springs?
I know these hot loads will accelerate wear. I also suspect the heavier springs might offset some of the punishment dished out by these loads. However, being the action of the spring returns the slide to battery much harder than the stock spring, will this increase unforeseen types of wear or bullet set-back during cycling? I certainly don't want bullet set-back with Underwood ammunition!
I'm interested in hearing from those using heavy springs with hot loads. Have there been any mysterious issues encountered?
Thanks in advance!
