also keep in mind it all depends on what you are trying to achieve with the gun? do you want it to have more power, smoother action, or are you happy with how it performs and just want to improve it as is, or maybe you just want to have fun doing a build that is unique to you? are you on a budget? these mods can add up and you could easily end up putting a few hundred in upgrades in a $70 gun. im not trying to discourage you, just trying to get you to consider what it is you actually want to do and plan accordingly before jumping in head first. there are many things you can do DIY by taking it apart and removing burr in machined areas, the trigger and sear, some polishing here and there and all of these things will improve its function without costing much more than some time. do some research, study the EVP, ask many questions. there are a lot of people here who can help you. the best mod is the long steel breech and most all would agree. but, you lose the stock rear sight and have to buy a sight that works with it like a williams or a MIM sight. what it does give you is a solid platform with a dovetail for scope mounting and a stronger hold on the barrel. here are a couple threads to give you an idea...https://www.gatewaytoairguns.org/GTA/index.php?topic=138633https://www.gatewaytoairguns.org/GTA/index.php?PHPSESSID=e954948fe94de2ab9cf24294ace04a00&topic=159203.0here is a thread i started and many people chimed in to help me with my newest 1377 build. maybe some of their advice will help you as well? https://www.gatewaytoairguns.org/GTA/index.php?topic=185793.0
Modifying a stock Crosman hammer with flutes is not the easiest job in the world, you can't easily do it with a ball mill, because the hammer is case hardened.... You can grind slots in the sides with the corner of a grinding wheel, but it will look exactly like that is what you did when you are finished.... That is why most who want to reduce the area in contact with the inside of the tube just grind flats on the side.... In addition, flats will remove less weight, which may be good or bad, depending on the results you want....Bob
Thank you for your insights. As I am ordering the kit from Alliance, I will ask him to match the barrel port to the TP since we're still waiting for the barrels. Thank you for letting me know.
