[Broken firing pin springs?]

try 1911 FP spring cut at 0,80 to 0,82"
dont know what life time is normal but I run this spring up 10k rnds with hiperfire trigger

[Short stroke bolt w/ LRBHO..?]

I use hiperfire,
when lowest part of ramp (because short stroke) not overruning highest poit of hammer,
trigger not reseting reliably

I have good experiences with 648

[Short stroke bolt w/ LRBHO..?]

just a hardened steel wedge (with radius) weld-on at original ramp (none milled slot)
380g bolt + 150g magnetopneumatic buffer (own construction) rifle spring
aluminium spacer + wave (materiál of spacer depend at PF of used ammo - higher loads works better with Delrin spacer)
love it

[Short stroke bolt w/ LRBHO..?]

third part is about trigger reseting by cancellation of the bolt ramping  

 

[Short stroke bolt w/ LRBHO..?]

second part
useful when the slide stop does not capture bolt just 0.02 "
realised by laser weld-on
 

 

[Short stroke bolt w/ LRBHO..?]

this is my solution, hope it will will help someone (for Glock magazines)
my SS are defined by 4.75 " OAL of compressed buffer + spacer

Any idea how much that weighs? 

 

[Skeletonized Hammers]

I made in the past a few simmilar designed hammers under 20g with no problems during using
and I believe you can find pictures of even lighter ones here in correct thread

[Which 9mm mags for ss?]

i have tried ETM, Tripp, Metalform, DP

ETM - terrible load into the gun when is full loaded

Tripp - terrible unload from gun when is not total empty

Metalform and DP - both same (same tubes, same springs and followers), work flawlessly, no problems with loading or unloading gun (STI-RM)

[Where do you put your thumbs..]

My grip is a bit exotic :-)
