I am the PROUD owner of an M9A1 and S9. I bought the M9A1 used with some custom "modifications" and the S9 new from Davidson's. Many thanks to the members of this board and over at GT for their insightful postings. Without all the informative posts, I would not have run out to purchase the S9 so quickly. The detailed slide disassembly and cleaning were helpful posts. I have a technical question. When dry firing the S9 I have found it not to reset sometimes. This has only happened once with the M9A1. If I do not rack the slide all the way the trigger does not seem to reset always. This has not happened when firing, which is good because I would consider it a major problem. Here is the problem: After dry firing with a standard full pull length, I hold the trigger to the rear and rack the slide only about an inch/1.5. I allow the trigger to click as I release it under pressure. When the problem occurs the trigger only clunks to the rear and a firing pin slap is not heard. The trigger just "crumbles" without firing. If I release the trigger fully, the pistol will cock and a normal firing pin slap is heard. To restate: when the trigger "crumbles" on reset, I must release it fully for it to fire, I do not need to rack the slide. Any ideas? I am mildly concerned because I have had 0 FTF at the range, yet. I appreciate any response. Thanks again for all your help in the past.
