Some IDPA stages have the bright idea to start with the gun in the IDPA box.
If you have to hammer your gun into the box... no bueno... it isn't coming out fast.
My Lim Pro has had three different experiences in three different boxes:
- One: Just jiggle it and it will go in (wood box)
- Two: Ah.. push it in (wood)
- Three: No go (some kind of hard plastic)
There needs to be an "official box" that is manufactured consistently by a single source that is the only one valid for competition, or, there needs to be an official ruling on this gun. I'd expect neither to take place any time soon.
Lets be honest, Tanfo manufacturing is not the most consistent thing on earth, and it wouldn't surprise me at all to see two different straight-off-the-line guns have a different experience in the same box. Then some people's guns develop more natural wear than others.
Depending on what safeties you use, you might have to look at the width also.
If I was highly committed to shooting IDPA long term with a Lim Pro, I'd just cut down a few mm off the beavertail, and safety if neccessary, and roll in ESP.
