Good gun, but yes it's long and heavy. I had a 25 cal I modified myself to produce 60 ft lbs and added a 400cc can to increase shot count. I adjusted the hammer spring, the regulator, and shaved the trigger mechanism cuz it was ugly. Additionally, I worked on the cocking mechanism because the increased hammer spring tension only made cocking it worse. Overall it's a super easy gun to work on, but if you're not comfortable I recommend to leave it to peeps who are. Hajimoto is the man and has some awesome informational videos, and is more then willing to help answer your questions. Additionally, he does sell gauntlets he has worked on as well.
