Just got my AXG frame in along with some orange Lok grips. I think it makes the Fuse look REALLY good. Feels better in the hand as well. Very solid. They did something different with the trigger guard undercut. Very S&W 3rd gen feeling. I think it elevates the look to a “professional pistol” status. Attached File Attached File |

Oooohhh yeah. That looks good. I really want an AXG frame for mine, hust dont want to pony the dough up for it. Two weeks after I got the AXG frame for my 320 my dept discontinued use of the 320. |
I don’t like making plans for the day. Because then the word "premeditated" gets thrown around in the courtroom.

Update: Took it to the range yesterday and ran 150 rounds of Blazer 115 through it. After the first box I started to notice my group size getting bigger and the group drifting to the left. By the end I was certain the barrel needed a good cleaning. When I got home I noticed that the front of the FCU is ridiculously loose in the aluminum frame allowing the FCU to slop side to side. My Ruger P89 has less movement. I'd be embarrassed to show someone this pistol now. The problem is the trigger is attached to the slide via the FCU which has a tight fit to the slide. This allows the trigger finger to open up the group size considerably left and right by moving the slide during the pull. I put the original Fuse poly grip on and it is tight again. So, in short, inside of 150 rounds the gun beat itself to death. Did some searching online and this is a common issue with the P365 and aluminum SIG frames. Not usually at 150 rounds but they still loosen up. People that have contacted SIG say the response is this is normal. One person even said SIG told him that you need to replace the rear takedown pin every time you remove the FCU. WTF? I'm too pissed to call SIG for the next few days. Looking at the design there is so much room for improvement. The front sliding metal piece that interfaces with the front of the FCU needs to be ditched in favor of a sacrificial polymer piece that fits TIGHT into the frame. |

That is a shame and should not happen. 150 rounds is nothing on a pistol frame or so you would think. Does it have a warranty period for it? Does the slide have a lot of play on the fcu in the grip module? On a side note and not meant to compare but I have ,(actually 2 of them), an Icarus ACE EVO aluminum grip module on mine and it is super tight to get the fcu in or out. There is no sign of wear but I only have 200 rounds through it and it still looks new. I say that as I can't see the aluminum being that bad unless it wasn't treated/heated/manufactured correctly. I researched and noticed AXG grip modules and see it is a common issue but that seems very wrong. For the price that they are, I would be pretty upset about that too. I hope you can get this resolved. |

I hope you can get this resolved. The FCU to slide fit is still very tight. It’s the FCU moving around inside the AXG frame that’s the issue. In my research, I did indeed find this a common issue with the SIG manufactured frames. Comments on the aftermarket aluminum frames indicate that they are holding up well. SIG uses a sliding metal piece (presume steel, haven’t stuck a magnet on it) to interface the frame to the front of the FCU and tension is provided by a piece of molded silicone rubber. If they made this sliding piece fit the frame better the issue would be resolved. I can see what SIG is trying to do with the design - provide a somewhat tight fit even with varying tolerances on the FCU length. I still think the better solution is to use injection molded nylon like PA6/PA66 to replace the current steel piece. As the piece gets beat on through recoil it will spread itself out and get even tighter. The part could be produced for 3 to 5 cents and sold in a three pack. To replace, drive out that front roll pin, remove, install new. Heck, I think that front roll pin is superfluous anyway, just omit it. Thinking about high temps in that area of the pistol I would go with Minlon 10B40 BK061 40% mineral filled PA66. Melts at 505F. Should survive everything except a guntuber burn down. The new plastic piece would be an easy drop in upgrade. Anyway, I put the original frame back on and tested it last night. Groups and accuracy returned to normal and I’m happy. The Fuse is just such a great shooting pistol. |

Developed a quick fix to test. Drove out front roll pin and removed the front block from the frame. Cut a piece of plastic to lay in the channels that hold the front block then hammered the block into place wedged tight by the plastic strips. Nice and tight. I think I’ll drill and tap the ears of the block for tiny hex set screws then carefully adjust those to eliminate side to side play. In my gun the front block is slid all the way forward when the FCU is in place. No fire and aft movement. Here’s a pic before cutting off the excess plastic. Note that there is a plastic strip on both sides. Attached File |

Update: After removing the front sliding piece from the frame that interfaces to the FCU via two triangular tits, I removed the blue silicone rubber "spring" from the front of the sliding piece and replaced it with a solid nylon piece I crafted from an M3 nylon screw I chucked up in a drill and sanded off the threads. I made it small enough to slip in and out of the hole without sticking. While in the hole, I cut it to length with about 6 thousandths protruding. When I reassembled the pistol the FCU was a lot tighter to get in place but once pinned in and the slide attached, movement is the same or even slightly less than with the polymer frame. Problem solved! I could drill bottomed holes in the sides of the sliding piece that surrounds the recoil spring and install nylon spacers in there as well to tighten it up even further but at this point I'm happy with the results. |
