Sorry. That sucks. Hope they get it sorted out for you.I watched Garand Thumb's video and picked mine up on Sunday anyway. Went to the range with a stack of mags and a FN Browning. Some things worked well, some not so much. No complaints on the ergonomics and feel, but there were some functioning issues that I think will be fixable. All but one...maybe. Accuracy was acceptable, grouping a couple inches to the left at 15yards so some minor sight adjustment. It fed round nose ball and flat nose 147gr just fine.
1. Magazines. It comes with one Mecgar so of course my Mecgar branded mags were fine. None of my OEM Browning or FN mags fit. The magwell was too tight. That will get a call to SA tomorrow. I haven't heard that as a problem from any of the online reviews so either they took it on faith that Browning mags worked, never tried them, or in fact they did fit in their guns. I took off the grips and if you aren't familiar with the Hi Power, there is a flat spring at the back of the mag well that provides tension to the sear. I think that may be what is pressing against the magazine and preventing easy insertion and ejection of the magazine. I need to disassemble an OEM gun that handles both magazines and put it in the SA35. If that solves the problem, it is an easy and relatively inexpensive fix at about $16. The extractor is $26.
2. Thumb safety. The safety feels good, but I noticed a heavier trigger pull on the 2nd shot than the 1st. The safety position is not the same as a 1911 and for me at least, it doesn't work to rest my thumb on top of the safety, so it is under. With recoil, my thumb edges the the safety up just a scosh (close to, but more than a RCH). The gun runs, it fires, but it makes the trigger pull harder as the sear has to push the safety back down that little bit. I'll have to search for a solution. Either slight alteration of my grip or mechanical alteration and the latter gives me misgivings. If changing my grip a little solves the safety/hard trigger issue, I think I'm good.
3. Garand Thumb particularly noted the extractor as a problem and I experienced it several times in less than 100 rds. The extractor failed to extract and running the slide wouldn't cause it to snap over and extract. But the fired case would fall out of the chamber once the slide was open and the gun was tipped. The other people who complained about this replaced the extractor with a Browning/FN extractor and the problem was solved. So that is the easiest.
Am I disappointed? Yes. There is a lot of positive to this gun, so any failings are disappointing, but it is very likely this will be limited to the early production guns. Garand Thumb noted it on mid 500 serial numbered guns. Mine is mid 1700. I called SA this morning and got an RMA for them to fix it. We'll see.
