I've looked up what hand lapping is and now I know it's not, as the name would suggest, a bonding ritual between man and rifle.
Please excuse my noobishness but as the XL7 has a user adjustable trigger, what would I ask to be done in a trigger job?
A smith will go ahead and adjust the trigger as you could (but might do it better). It will include eliminating creep and any lag, and also the pounds needed to release the sear. He'll also do any needed polishing and burnishing of the contact points so the break is crisp and clean. The trigger will probably come from the factory with a break of about 8 pounds or more, and you'll want to lighten that for sure.
Congrats on the purchase, and please let us know about the XL7 and it's performance. I've been interested in that gun b/c of the good reviews and very affordable price.
