Wow, thanks for all of the responses. I am thinking of just sending it out to one of the memebers/smiths mentioned above and asking to have the gun inspected, paddle added, and refinished. Also I failed to mention it seems like the lower grip assembly (metal) is a little loose. Would replacing it with a plastic one tighten it up?
I would take everything apart and clean, in particular the chamber and bore, then do a little more shooting to see how it shoots and groups with a couple different types of ammo. While like the Federal XM193 I am finding that some lots are not that accurate, with groupings of over 2 MOA using scoped rifles that shoot under a MOA. What is even more surprising is the Wolf 55gr ammo has been shooting close to a MOA under the same conditions. My control "low cost ammo" is Federal American Eagle in the Red Box (FMJ but use to not be the M193). Reason for doing the testing now is that if you ever needed to have a barrel replaced, then when you send it out for a refinish it the perfect time. Note would consider having the A3 stock refinished at the same time.
Note if just the plastic grip is loose, look for a screw to tighten up, if the whole plastic grip and trigger housing / frame (part the comes off and has the trigger pack in it) is loose, then would check with the HK smith of your choice, if you are sending it off anyway.
Have heard good about both smiths listed (I have close friend now days that does my work, since Terry is semi retired, excluding what I get from Mike and his team), I would check on the delivery time of the project as good HK smiths tend to get back logged (i.e. in the old days that could mean years ;-). I know that Jeff has been getting great reports on turn around time, pricing and quality of work.
