Ill post a pic but the plug looks like the one you would use if installing a magwell. The difference is it is designed for the compact. It is about 1/8" shorter that the standard. I have tested the gun with 35 rounds of reloads. I am shooting 147 fp blue bullets loaded to 1.125 oal with 2.8 grains Titegroup. The primers are Winchester SPP. No light strikes, and no feeding or ejection issues. The only thing that didn't change is the trigger take up and the reset. I found a full size plug online and will install it when it arrives. I'll post the trigger pull info and reliability once i have a chance to put some rounds downrange.
