Hi Power in 357 Sig

I tried searching and nothing came up, so I apologize if this is a repeated topic.



I would like to convert a 40 Hi Power into 357 sig.



I have a few questions about it:



Is it a reliable platform in terms of feeding and extracting in this caliber?



Is the recoil uncontrollable?



Anything else I should know about?

Hi Power in 357 Sig

Howdy Mr. Jager1,



Yes sir, I have done this using an EFK Fire Dragon barrel. That particular barrel is simply a straight drop in with no fitting required. Just swap barrels, use the same recoil spring and the same .40 magazine. Your capacity remains the same - 10 rounds of 357 Sig.



Accuracy with this caliber is very impressive and I find the recoil to be less than what I feel with the .40 S&W. The .40 is more upward to me, while the 357 Sig feels more straight back. I have some medical issues, and I can fire more Sig rounds than I can .40s before my hands begin to bother me. That is another plus for me about the 357 Sig round. I shoot it getting tighter groups and at a bit faster pace, and can shoot more rounds.



About the only other thing I can tell you about the 357 Sig round is that it can be very addictive. If you have never fired the round before, I think you will be pleasantly surprised.



If you have any more questions just yell.

High cost of ammo for the Sig 357

Heh. Ironically, however, it seems that every Walmart sporting goods department I've been to in the last several months has .357 Sig ammo on the shelf--even when they have no other rifle or handgun ammo!



Were it me I'd plan on getting the dies, shellplate, etc. and reloading my own.

My experience as well. I personally do not care much for the blast generated by this cartridge.

Hi Power in 357 Sig

Howdy folks,



Of course my hearing is a bit "less than normal" these days. When I shoot I religiously use both Sonic ear valves and good shooting muffs. But I personally do not find the 357 Sig to have more blast than many other calibers I routinely fire. To paraphrase a good friend here, Mr. Chris, detailing his first venture into the 357 Sig, he prepared himself for the world to come to an end when he fired the first round, and was shocked .... when nothing happened. (Grinning).



As far as reloading goes, I definitely would suggest that to anyone who is interested in this caliber. I was curious to see how things would go loading my first bottlenecked handgun round, and had read that I would have constant problems/issues with it. Much like Mr. Chris, I prepared myself for the worst, and nothing happened. It is a very reloader friendly round in my view, and is no different from loading any other handgun round to me. Except that it is very accurate and seems to like many powders and bullet combinations.



In their revised number 2 manual Accurate Arms (now Western Powders) said it was the most consistent and accurate handgun round they had ever worked with. All of my pistols converted to fire this caliber will easily shoot it far more accurately than I can.

Hi Power in 357 Sig

Minus the reloading (which I don't do), my experience with .357 Sig is the same as Twoguns'. I am a big fan of the round and carry it on duty in a P229. Had a G27 with a 33 barrel in it which was much easier to shoot than in .40. My only concern with the round in a HP is the usual rumor about shearing off the locking lugs. Good luck.

Hi Power in 357 Sig

Gents,



I tested the .357 SIG barrel in a FN HP 40 and it ran perfectly. The same barrel does not fit as well in my BHP Practical and I've been leary to shoot it until I can get it properly fitted and not risk damaging the pistol/barrel/shooter.



Personally, I think that the .357 SIG caliber in the .40 HP platform may just be one of the really effective set ups out there. Just my humble opinion, mind you.



Next time I think I'll go for a "fitted" barrel to ensure there's no doubt in the back of my brain housing group!

Hi there all,



Well, Mr. Twoguns did start me on the path of experience with the 357 SIG and it is a great cartridge platform.

If I had the means, funds and opportunity, I would definitely consider adding a .40 S&W HP to my collection and immediately convert the barrel to 357 SIG.



Mr. Twoguns was quite correct. When I first fired the 357 SIG, I expected it to act like shooting a .357 Magnum through an Airweight S&W snubby. Of course, nothing happened except the big grin that came over my face!



I hope that you take the opportunity to give it try. I do enjoy owning multi-caliber convertible handguns.



Chris

Hi Power in 357 Sig

Howdy Mr. Jager1,



Mr. Wes brought up a very valid point regarding this conversion, that I failed to mention. My pistol that I have converted and am very pleased with is an FN HP .40. He tried it with both an FN HP .40 and a Practical, and decided to avoid the combo in his Practical.



I know of at least one member here, who used the EFK barrel in his Practical and had lug issues.



So the only conversion I can speak from personal experience from is of the FN HP. I have at least 3,000 357Sig rounds loaded with 125gr JHPs and some factory Winchester 125 BB rounds through mine with zero issues.



I am surely no expert on this or any other topic in my mind. But based on the experience of members whose experience I trust, if I had a Practical .40 I was thinking of doing this conversion with, I might not jump as quickly. If we do have any members who have converted their Practical .40s with no issues, it would be good to hear from them, so we could try to evaluate that combo.
