I bought a 40 S&W AMT Backup, and reamed the chamber out to 10mm Auto. The magazine is 45 ACP length, so removing the spacer inside allowed 10mm to feed like a charm. If you do a google search, there is a fairly exhaustive writeup about the process that another fellow put together.
The problem is, this thing kicks like a mule. I am fairly recoil insensitive and am more worried about what this is doing to the gun than to my hand. I believe that the recoil spring needs to be greatly strengthened. At the moment it seems that the slide is slamming into the back of the receiver, giving the large amount of perceived recoil. The whole gun is not that much lighter than my Glock 20, though I suppose the slide is quite a bit lighter.
I've checked the Wolff site, and they do have springs for this gun in its 45ACP configuration. I know that 45ACP is much lower pressure than 10mm. Am I correct in assuming that I need even stronger springs than those?
Other than measuring the spring rate of the current spring with my bathroom scale and trying to find something of similar dimensions, but higher rate at the hardware store, do I have any other options to pick up a stronger spring?
