All current G43/G43X/G48 Glocks should be equipped with the - connector which reduces the trigger pull slightly. The original G43 pistols did not have the - connectors and had heavier trigger pulls.

 

There have been three different OEM connectors for these small frame models. Only two are made today.

33215 - UNMARKED ( ) -> Original standard connector used in early G42 and G43 pistols. Produces a peak pull around 6.5 lbf. Now discontinued.

33564 - MINUS (-) -> Present standard connector used in G42, G43, G43X, and G48 pistols. Produces a peak pull around 5.5 lbf. Replaces 33215 connector in all pistols.

33847 - PLUS (+) -> Optional heavy-pull connector usable in G42, G43, G43X, and G48 pistols. Produces a peak pull around 8.0 lbf.

 

Great information, Mike.

 

FWIW
Note on the #33564 - MINUS (-) connector.
Apparently, there are two different kinds of #33564 “-“ connectors: One with both the “-“ AND the number stamped on; and the other with only the “-“ but NO number stamped on. Other than the presence/absence of “33564” stamped, they are identical in appearance and function.

I own two G43s, both Austrian made, purchased brand new. Both came with the new “-“ connector and the box labels say “5.5 LB.” But the older gun of the two (i.e., SN# BCxxxxx) came with former type and the younger gun (i.e., SN# BFxxxxx) came with the latter type.

 

I recently got a new to me 43x & feel that the trigger pull is kinda stiff. Did any of them come w/ the unmarked connector? There is no minus on it. I ordered a minus connector to replace the one I have to see if it helps. I was just curious.

 

43x should come with the minus (-) standard. I’d be willing to bet you have it, you just don’t see the minus mark.

 

I'm looking at a G43 for my Brother & all this info will come in handy when/if he decides on one..
The G43 will have to beat the S&W M&P Shield & it's also available in 40 S&W + costs $249, where the G43 is $319..
