dcavenPorting my P220
I'm interested in porting my P220 .45. I will likely go with Magnaport but am open to suggestions. What I need help with is ammunition. Goal of porting the weapon is to reduce muzzle flip and more quickly get back on target. I practice Mozambique drills and want to be able to train to run through them at light speed. This will require different ammunition. Someone recommended speaking to an IPSC shooter. I'm looking for a smaller bullet traveling fast enough to really make use of the the porting. I will make the ammunition. Any suggestions would be helpful. Thank you.

RHINOWSO....aaaaah.... ever think about a P226 in 9MM?

colt_saaAn expansion chamber style compensator will be much more effective with a 45 ACP cartridge then Mag-na-porting
Mag-na-porting is more effective with high pressure cartridges like the various magnums

js1badstiMagnaport would be a good decision and probably a 160gr bullet loaded with a slow powder to feed the comp ports.Thats what a lot of open shooters do.

Of course. P226 is a wonderful pistol. I have and have had a P220 for many years and am focused on improving it. Between porting and load development, I'm confident I can reach my goal. Thank you.

Thank you and thank you for not suggesting I buy a P350 or whatever. I will write down your advice and will explore it. Take care.

I understand. This is my carry weapon. I would rather not add to the length of it. Trying to work with what I have to achieve a specific result. Thank you.

hrcjonNo comment on the porting idea per se, but you say this is your carry weapon. Have you shot a ported gun with loads to feed it in the dark? Its pretty impressive and not in a good way.

I understand your point. I'm sure you have much more experience than I do. In my limited experience, once I had the principal target in line, I relied on speed and shooting experience to execute the pattern. Paid no attention to weapon sights nor to vision at all. I am interested in repeating that process at twice the speed should it ever be necessary. Thanks.

hrcjonShoot it in the dark a few times, just for the experience so you know what you are dealing with.

dcavenI will do so but I'm not sure you understand. Once you have center mass in sight, everything after the first shot is reflexes. If you have distance, you likely have a way out. Just my thought. I'm completely ok with being wrong, everyone has to decide. In my experience, once I had him, I had him. I did not need visuals. I needed speed so nothing would come flying my way.

jackimoeGecko45 was once facing a similar issue. He disappeared though and I never found out what his conclusion was. Good luck with the experiment though.

StramboAt the risk of feeding a troll...you’d be better off with professional training and your night vision intact. The difference in split times with porting wont matter in a gunfight. If muzzle flip is that bad your grip and stance probably sucks.
Adding movement would up your survival chances way more.

I'd definitely suggest quality training. What you're describing is very much akin to "point shooting" and that has been effectively show to fail with multiple target engagements.
Learn to use the sights and not rely on "Not needing visuals". You absolutely need to use visuals.

dcavenMaybe so but the dead guy would likely disagree. Trying to improve on a proven concept, not trying to reinvent the wheel. Thanks though.

casI would suggest you do not.
Personally I don't think the gains are worth the cost and "damage" done to your gun.
A 45 ACP is relatively low pressure, so porting/comps don't work particularly well.
(I own Magnaported guns that I wish were not).

dcavenPlease expand. Is there damage and if so, what kind? If I speed up the round, wouldn't the pressures increase? Honest questions.

I've had training and am no troll. I'm trying to split times, yes. In a gunfight, it does matter. Not a major veteran but have been in a gunfight. Hence, the question.

Movement is not always an option.

I'm pretty sure what is meant here is destroying a good slide and barrel. And I would add for a negligible gain with this cartridge and IMO potential detriment. But too each his own and that is not any sort of criticism.
Your tactics discussion doesn't make any sense, but they are yours to execute so OK.
