I have an IMA set. The set assembles nicely -a little stiff, but new leather generally is. The leather seems to a little on the thick side too, but maybe that’s because it’s still very stiff. A pistol fits the holster well but that’s it. A loading tool barely squeezes into the little pocket, and it won’t latch if the loading tool is in it (way too tight.) magazines are also a very tight fit in the double pouch. The stock will latch on the a pistol, however. The cleaning rod that comes with it has an enormously large barrel and the rod is electro-plated. That said, no one will ever mistake any of this for an original.
Bottom line, if you want something to display without risking an original rig, buy this. Likewise, if you have a shooter LP.08 and want to use a stock this one is ok too. I took the leather off the stock and use it and one of your GT Special trommels

with my shooter LP.08. (Truthfully though, my LP.08 shooter is probably too nice to be a shooter, but it’s also not nice enough that most folks would want it in their collection.
