I just took out my LW 40 conversion today. Put 100 rounds of 180 gr ultramax from cabelas. No failures at all. I'm also running the 22lb spring and SS guide rod. I'm a horrible shot but I managed to shoot a couple groups with all five shots touching at 25 feet. My best groups ever. Although it shoots a little to the left.
Also shot the 22lr conversion for the first time, what a bunch of fun! I shot off 400 rounds. Its great to fire off as many rounds as you want without giving a second thought to the cost. My finger hurts from the trigger and my thumb from loading the mag I couldn't shoot anymore. Gloves next time lol. Only 2 or 3 failures in the first 25 round or so. the other 375 shot great.

I sleep better in bear country with a 10mm under my pillow!
