Let's say I have a hypothetical FFL who will transfer an out-of-state purchase of a non-compliant firearm, we'll call it a S&W M&P45. So, again, hypothetically, I end up as the legal owner of this firearm. At some point down the road, the M&P45 becomes "compliant". Would I, at that point, be able to transfer this firearm to another LTC holder via FFL? (Yes I know I could always transfer via FA-10) I understand that this particular firearm would not have the MA trigger, but would it be scrutinized that closely? I've never had an FFL use a trigger pull scale when doing a transfer! Just wondering, and thanks for any opinions...
