P938 ammo recommendation
 
Off to the range with a new P938 Extreme. Is there an official recommendation on a preferred round? My plans are to put 500 rounds of FMJ through it before trying self defense rounds.

advice from P938 owners please.

whatever you can get at the most reasonable price that doesnt have feed issues. so far I have had good luck with Cabela's Herters brass (it was on sale for 9.99 per 50 a few days ago) and Fiocchi shooting dynamics 115 gr for around 11.00 per 50. I have shot probably 1,000 rounds between the 2 brands and haven't had the 1st problem with the 2 brands in my mk25.

overall, mine seems to like 124 grain over 115. presumably the heavier round raises pressure, and racks the slide back harder, and the return has the energy to feed the rounds better

P938 ammo recommendation
 
As VetteGuy said, mine runs better with 124 grain. I like Speer Lawman Cleanfire, no smoke, better for my lungs. Ammo to Go has some good prices with 500 rounds.

i've never tried anything but the 115 gr stuff because it's worked and is usually a few $ cheaper than the 124. I will have to pick up some 124 and see if I can tell a difference.

I have had problems with feeding Hornady defensive JHP rounds. I have never fired them yet but just racking the slide to chamber a round only works 1 out of 4 or 5 times. The flat tips just get hung up on the feed ramp

That is a well known issue due to the JHP shape of those rounds. When I was talking to a tech at Sig he said to not use the Hornady Critical defense rounds in these guns.

Did not have any trouble with the Magtech Guardian Gold or Rem Golden Sabre just this week.

i have run many different brands though my 938, including hp's, and never had one failure

I'd suggest only using 124gr for the most part.
A lot of P 938s do not like the 115 gr FMJs.

+1 here. I've found that mine cycles 124gr better.

I like, and carry, Federal HST 124gr, standard pressure.

sig78257 12-22-2014 04:58 AM

I also carry Federal HST 124gr, standard pressure. For practice I like 124 gr Blazer Brass.
Haven't had any problems with either. Recently bought some 147gr HS to try but haven't had a chance to shoot them yet. Early 938's had feeding problems usually because of rough feed ramps, so Sig was recommending 124 gr. Once Sig polished the feed ramp on my first 938, it fed everything including DPX 90 gr and any 115gr I tried. I know have a newer 938 SAS which had one failure to extract in the first mag., no problems since. (Remember to check the guide rod when you clean the gun, they tend to eventually unscrew).

I keep hearing this story about 124 grain bullets as best. I have over 500 rounds of 115 grain bullets of various manufacturers without any problems whatsoever. As for carry, 147 grain Golden Sabers. Why? Because they are the cheapest.
