Went to the gun show in Tulsa today, found a used M40-A1 with 2-12 and 1-10 round magazines for $385. Not quite the $299 deal that Ikorman found last week, but good enough for me to take home. Ran a box of 165 gr. CCI Blazers through it trying to make it jam, tried limpwrist, etc. no problems of any kind. The aluminum cases (can't call it brass) landed in a 3 foot circle to my right, except 5 unaccounted for, probably lost under leaves on the ground. I think if it will handle Blazers it will handle anything, at least Blazers have always been most likely to cause problems in other guns I've owned. Didn't fire for accuracy, but I'm sure the gun will shoot better than I can right now. I'll look for a 357 Sig barrel for it once I get over paying this unplanned purchase. I did NOT expect to find a used M-A1 today.... \/ I see by the replies that using Blazers wasn't a significant test. My previous experience with Blazers was bad in the S&W Sigma (though it didn't feed anything well), Colt Commander, Browning HiPower, Glock 36. My Hk P7M8 never had any problems with Blazers though, but it eats anything 9mm without hesitation. I hope this means my M40-A1 is in the same reliability class as the P7.
