Yup, that's the key, the barrel lugs prevent the swap. Over in the GATE Glock Pistol Forum
, our resident expert JR Shepard gave this humorous warning about such an experiment:
"No can do. The locking lugs of the full size G20 are different than the locking lugs of the compact G29. BTW: If you get it in there, it is going to lock up so tight you will have to pay an advanced Armorer to get it out.... and then he will tack on an additional "stupid" fee for doing so!"
