Antzrus, you continue to amaze me!
Assuming the "firing" (clothes) pin on your current gun is about 3 to 4 inches, I estimate that you have about a 35 to 50 mm projectile on that thing, which I accept as proof that you have the bigger (bore) gun, compared to
myother45isalesbaer, although it still doesn't come close to the M777. I also love the built-in additional ammo supply holes on your gun, but you are going to be significantly short compared to the Les Baer's magazine, unless you are towing a supplemental ammo limber!
In any case, if you ever do meet
myother45isalesbaer in person, I respectfully suggest you lay down your weapon and concede defeat, since as we all know, size isn't everything!

Just my recommendation: us old farts have to stick together and look out for each other.
I too love my M45X and when I bought it there were very few vehicles under $80,000 (CAN) that could take it. While my boy racer days are long over, I am not totally immune to the occasional challenge, and have been known to sometimes (to the annoyance of the MRS.) shut down and teach a lesson to some uppity young'un in an over-modified rice rocket. She just doesn't understand that male competitive thing!! Having said that, as I have gotten older I have come to enjoy and appreciate my creature comforts, too. So to me my M is the perfect blend of lots of power and driving comfort, and I don't intend to get rid of it anytime soon!
P.S. I am also very happy with the 14-speaker Bose 5.1 system in the car and my ears were never subjected to close range heavy artillery! I have studied music formally and have a pretty sophisticated (and powerful) Yamaha/Polk Audio surround-sound system in my entertainment room. With the ambient noise in a moving car, I think a lot of these guys that complain about it are being overly critical IMHO! Most of them also never experienced the early single speaker radios and AM transmissions of cars in the 1950s or 60s. We have come a long way!
