cobverting a 40 Hi-Power to a 9mm

Discussion in 'The Browning Hi Power Club' started by jimsfinns, Nov 30, 2010.

  1. To all, I have a VERY lightly used .40 that I am thinking of sending to C&S for their conversion to 9mm. I'm just not a fan of the .40 and I like the handling characteristics of the beefed up slide. Does anyone have any experience or input with the conversion? Is there anyone else that I should consider sending it to? all comments will be appreciated.

    Just sell it or trade it for a HP in 9mm. It will be less headache.

    Novak's also does that conversion, as memory serves.

    just buy a conversion barrel (EFK) and buy some 9mm mags and you are good to go. The barrel has to have the 3 locking lugs to work in the 40 slide

    Just realize that the breechface was designed for the. 40 S&W. It is slightly larger than 9mm and could cause some erratic function problems. I'm not saying it will happen, and I can't say to what frequency it could happen, but it's just something to be cognizant about.

    I would feel perfectly comfortable sending any gun to C&S. Someone else mentioned Novak's. Both of those are top notch and both are world renowned for their work on the BHP. To the best of my recollection, when the FBI hostage rescue team used the HP, they were all built by Wayne Novak and his crew.

    My first Hi Power was a .40 and I did not care for it either. I loved my friend's 9-mm HP, but the .40 just wasn't for me. I found one load that was comfortable to shoot in that .40 HP, but the other loads I tried in it were just horrible as far as recoil and bite. I know there are a lot of folks out there who love the .40 HP, and I'm not wanting to start a fight, but that gun, in my honest opinion, was built from the beginning to be a 9-mm and they should have left it that way. The last time I looked at the Browning website I noticed that they were only offering the HP in 9-mm.

    The 40 Hi Powers are perfect for 357 SIG!
    I love mine!

    Poohgyrr trout fear me!

    C&S has a good reputation and can verify your Hi Power is running right, giving you some peace of mind. FWIW, I like the idea of being able to run both rounds out of the same pistol. Sig & Glock does the same with 40S&W and 357Sig in their pistols too.

    I've got a stock .40 BHP with a trigger job by Don Williams (The Action Works) that has both .357Sig and 9mm conversion barrels. A great shooting platform for all three. The C barrels are simple drop-ins and function 100%.
