BHP Trigger pull creep

Hi,
On a Browning Hi-Power pistol with the magazine safety - Is there a way to lessen trigger creep and generally smoothen the overall trigger pull?

I do no wish to remove the magazine safety.

Thanks.

Because of an elaborate series of links and transfer bars that make up the BHP trigger system, it is one of the most difficult trigger systems to work on. The motion of pulling the trigger changes direction through the various links five times before dropping the hammer.

Polish the top front of the mag, where the mag safety rubs. I took the mag safety off of mine. How safe is it, if it doesn't fire when you really need it?

Polish the mag disconnect, too. I did this and it helped some. Then I removed it :) Big improvement.

With the disconnect still in, some of the aftermarket mags I have, KRD IIRC, were much smoother than the Browning mags. I can't say one way or the other about smoothness of the stainless 13-round mags from Numrich because I bought them after I removed the disconnect.

So I guess polishing is the only way to go???:confused:

Thanks.

Hi John,
Did you remove the magazine safety yourself or did you have a gunsmith do it for you?

Thanks.

It is not hard at all,you just get nervous about scratching things if you aren't careful;) It's well worth the effort:cool:

Your welcome;) Just a hint that worked for me(done this 3 times now:) ),find a nice 6" or so vice,put a piece of leather on the right side of the frame,then a small diameter punch over the trigger pin ,on the left side of the pin ,and slowly tighten it.This gives you really nice control removeing the pin,rather than setting the punch on it and hitting it with a hammer:D


Good luck:)

4570Rick is correct. That trigger arrangement is one of the darnedest "around the corner, down the street" system I know of. Even the Luger is better.

In addition, the BHP hammer has a very deep sear notch, which is amenable to careful polishing with a "knife" stone. It can even be trimmed down considerably without affecting safety or reliability, but I don't recommend a DIY project unless you have experience.

I too don't recommend removing the magazine safety on general principles, but it and the magazines can be smoothed up and a coil or so taken off the spring. With that done, and a bit of grease on the safety, it will still work but have much less effect on the trigger pull.

Other tricks are building up the linkage parts with weld (tricky job) and fitting them carefully. The slide also may need work, as if it is not fitted properly, some trigger pull effort will actually go to raise the slide off the frame rather than toward disengaging the sear.

Although I have not tried it (I remove the magazine disconnect in every gun I buy that has one-I need my stuff to all work alike, as that saves on brain cells I need for other things) I have heard that some gunsmiths would vertically serrate the face of the magazine disconnect where it contacts the magazine.

In other words, the part that protrudes into the magazine well and gets pushed in by the magazine gets a series of vertical grooves cut in it.

This is said to reduce the surface area of the disconnect, and reduce attendant friction.

YMMV, of course.
