So, I changed out the grips on my SA 9mm from a set of Pachymar finger groove grips to a set of blue/black magwell bottom G10's.
In the process, I also changed out the SA arched ILS mainspring housing to an S&A arched magwell.
Immediately, the gun went from a buttery smooth cycling pattern to getting hung up with extremely gritty slide action.
The slide would actually hang up returning to battery as seen below.
For a minute, I thought that I must have damaged something or got some kind of metal filings or debris between the slide and the frame. I got all frustrated, and changed everything back to how it was before I started. The buttery smooth cycling returned.
This drove me nuts for two or three days. I've never had an instance where changing out grips or a MSH caused any type of malfunctions. Putting the grips on, they were a little tight against the magwell, but that was all I noticed.
Investigating a little further, I saw that the G10 grips were touching the extended slide release on this gun. Touching enough to put sufficient upward pressure on the slide stop to make it drag across the bottom edge of the slide.
Here is the contact mark from the slide stop when I took off the grips.
So, out comes the needle files and abrasive stones. Create a little relief where the slide stop comes to rest.
Now the slide stop drops enough to clear the bottom of the slide.
Thought I would share. Anyone else experience this?
Drove me nuts for a day or two until I got enough time to figure it out.
