I had an issue with my grip on the Sig as far as how desperately I could put a clench on it. The gun felt just a bit full and rolly-poly to me compared to my 1911A1 (and I always figured I had big hands) so I looked around for solutions.
Sig Slim Grips! They arrived in a standard blister type hang-packaged enclosure with logo, lettering and cardboard that appears genuine. Since I bought them on eBay they may be clever fakes made in China by slave-labor.
But I don’t think that’s the case, the seller has a good reputation and a large inventory. I believe they are factory replacement, and as the legal caveat on the back says, “A qualified gunsmith may need to install this (sic) part.”
Since the thicker panels aren’t holding it back it extends into the magazine well. Obviously the screws are now too long – the magazine doesn’t like it and won’t go in or out.
Meanwhile the left side grip isn’t quite lining up. The top screw hole places the magazine release cut-out in a tight fit, and cants the bottom screw off to the right. We can fix that. Grease pencil and Xacto knife to the rescue! Still the results are not real promising even with the screws tightened-down well into the mag-well.
The inner edges pin against each other and flare outward in a v-shaped gap. The inner edge where the grip panels meet impedes on each and needs to be shaved back so they don’t present such a wedgie – and the grip screws need to be relieved of about two full threads so they don’t penetrate into the mag-well.
As it stands in the picture (left) the magazine cannot be employed at all. If the grips screws are not fully turned-in they leave a gap that displays the hammer spring and strut – and would allow debris to accumulate and tie-up the gun – not an option.
So what now?? I dunno. The gun feels more grippable with the slim grips, but I need to do a bunch more work if I want to get them to fit. And the grip screws need to be shortened by at least two threads.
In stock configuration with the grip-screws cranked down tight they still don’t penetrate into the mag well at all. The slim grips at Sig are not advertised or described as requiring shorter grip-screws and the package does not list them as included either, but they seem very necessary.
Regular grips with stock-length screws that don’t impede into the mag well fit nicely together with no gaps, wedgies, or misalignment.
What seems clear to me now is why modern polymer-frame gun manufacturers are emerging with grip-frames that are designed with removable back-straps and other bits and pieces to suite various sized hands.
It’s easier than re-fitting grips that are a bit wobbly or incompatible without further modifications, sanding and filing and all that old-style craftsmanship.
