Alright, been looking at the MP Core's and they look sweet. Is the 90$ worth the performance center? I ordered the Rmr07 but debating on the weapon? Any one have any input. I read a few threads but want to make sure it's worth it. Also debating on a x300 vs tlr1 hl? 9mm or .40? Basically for home defense and fun at the range. I carried a MP 40 and MP15 for a few years and miss the MP weapon.

Thanks in advance.
