+1send it to springer precision. he knows what hes doing. $30+ shipping the slide. vs $65+ shipping to springfield. Springers turn around time is in days not a month like Springfield.
Most likely. An FFL can use the USPS, I only paid like $16-17 when I sold my XD-45 BUT my FFL charged me $25 for the transfer service ( they actually earned it on that one as there were some problems on the buyers end )SA just did some work for me and it only took a month. They installed Trijicons, hard chromed it, and installed a solid guide rod. I'm sure yours would take far less time since they had to send mine out for hard chrome.
B.T.W. I was told just after shipping my pistol to them that using a f.f.l. dealer to ship is cheaper.
