Hello. I have ordered a spring kit and am on the verge of tuning up this rifle. Does anyone know if this thing can be slicked up too much? It has issues not feeding 38sp like it should.Guide rails seem to be proper distance etc.All detents ,notches will be maintained, I don't want the lever to become floppity or it to become unsafe in some way. Any help?:confused:

Well my spring kit arrived today and apart the 92 went.:bleh: I say now in my 50 years of dealing with firearms I have never seen a more disgusting mess. This gun looks as tho the parts were made in a Pakistan tribal forge,and all the machining[only the bare minimum to make it functional]was performed with a rough grit grinding wheel.:mad:My nastiest Italian BP revolver is a masterpiece compared to this thing.:( This gun was purchased brand new about 9 months ago. One good thing,it can only get better from here. I am no longer concerned about doing any damage or harming this thing.

I got down to business on this thing [after the initial shock].I had to spend alot of time with the essential parts installed in the reciever, cycling dummy rounds threw the path they take. I have a much better understanding of the what and whys of the tuning posts I have read.I continuously set rounds on the lift ramp, and brought them up and threw the guide plates into the chamber, with a dowel, and then the bolt watching very carefully.I relieved the entry into the chamber[ramped it slightly] to match the angle machined into the left guidance plate.That seemed to help an area of unhappiness for the cartridge.Polished all the pins,pin holes,spring contact areas,guide plate friction areas,action activation areas w stones 1000 paper then jewlers rouge. Installed Gunslinger springs,thinned spring at loading gate,cut approx 3" off mag spring,and lubed it all up.And refinished stock.The puma m92 kit is done for now.Looks and feels much better .Will give it the real test in the West in a couple days.;)

No dice with this thing working properly.During tests it still fails to feed 38s .Does anyone know the answer to this?When a 38 comes from the magazine on to the lift ramp and is halted by the stop on the lift ramp, what is supposed to stop the next round under spring pressure from following it and over hanging the ramp and jamming it.357s work because take all the space on the ramp and exclude any further rounds coming from the mag. The 38s must have that 1/8 " extra free space and something else must halt the rounds from the mag?That flipper on the left guide?

I just had the gun shooting in WV the last couple days and it is very smooth and has a very nice trigger now , and is very accurate:).I may have been too harsh on the producers of this firearm,but I am very particular about fit and finish and almost all my guns have been remanufactured in some way.This gun has a very particular problem/malfunction right from the box.The flipper/cartridge excluder[my name for it] on the left cartridge guide was and still is non functional.It does not do its job of metering the rounds out of the magazine,so they all follow one another in a row onto the lift ramp.The 38s are a problem because the stop on the lift ramp is calibrated for 357 length and they stop with the bullet nose at the front edge of the ramp and they act as their own excluder and work fine..The overhang of the round coming out of the mag [approx 1/8"] jams the ramp with 38s.I have many thousands of 38 cases and thats a resource I cant just disregard.I am going to disassemble again and look at what can be done.:( P.S. Watch out for that &%#$% collar ejector spring.I will make a special tool for that this time.

The spring is in.It does keep the next round in check when testing like shown in the pictures.However when loading threw the loading gate the 38 round does not have the length to push the #2 round, second round in order of firing deep enough to catch its rim on the excluder.So first cocking of the gun has a round overhanging the lifter and its all bad from there.Plus I think the spring was not right when recieved,but it is now!If I load it threw the gate and then open the bolt part way and push the #2 round up past the excluder then close the bolt she runs good,in my living room w dummy rounds..[there isn't an emoticon for how I feel]frustrated in need of a stick to use on the last round loaded threw the gate,or a longer finger.Tried that in WV but the lifter still jamed.Maybe that was a fluke.:confused:I'm not beat but I need a small rest. Stay tuned.
