I thought it would have had a higher peak pressure earlier so more susceptible to bounce due to smaller pressure cylinder diameter....we shall soon see, if i get a chance I will swap one of the triggers from one of my 80's (they all have rotating pistons so modified trigger sears) into the 77 over the next 2 days with an LGV spring and see how it does.

Really hoping this works well, very keen on going 23mm in the LGU also if it does, aluminium2buy on the bay stocks 25mm od 1mm wall in short lengths. To date i have never been happy with the LGU, its a fine gun but not a patch on my TX now, if the 77 is transformed with this 23mm conversion it will just have to happen in the LGU also along with a new trigger blade.
