[Question about reaching for 140 power factor on 9mm 124 grain load with Alliant Sport Pistol]

Thanks for the detailed explanation ZZT.  Great idea about checking debris on the target board.  

 

Will definitely try this out!

[Question about reaching for 140 power factor on 9mm 124 grain load with Alliant Sport Pistol]

Hi Guy, thanks for the response.  I was told by the gun maker that I should try and aim for 140 power factor to see a benefit from the comp.  I have a non-comp'd version of the same gun and it is shooting great at 135.   I think I will try the same load when the comp'd version arrives.  

 

Thanks again!

[Question about reaching for 140 power factor on 9mm 124 grain load with Alliant Sport Pistol]

Sorry for the newbie question...  

 

I am looking at purchasing a single port compensated 9mm pistol and have read that I want to be around 140 power factor for the single port comp to be effective.  

 

I am currently loading 124 grain jacketed with 4.3 grains of Alliant Sport Pistol.  With this load, I am getting about 135 power factor (average speed around 1085 to 1090).  

 

Alliant chart said I can go up to 4.7 grains for a +P load with Sport Pistol.  I am sure that if I go to +P load at 4.7 grain, I will be at or above 140 power factor.  

 

I have heard that it is not wise to use fast burning powder to achieve higher power factor as it causes too much pressure; so I am a wondering if is safe for me to try and get 140 power factor with Sport Pistol?

 

I have a lot of Sport Pistol so I would prefer not have to change to another powder if I could avoid it.  

 

Any advise would be greatly appreciated.

Hi everyone,

 

Have a newbie question to ask...  I just purchased an Atlas Athena as a range toy.  

 

It is a "2011" type 9mm pistol with 4.6 inch barrel with full dust cover. 

 

Been looking for holsters for this pistol but found only a few makers that specifically make one for this pistol; but not really interested in the ones I saw.  

 

Wondering if any all all "2011" double stack pistol holster should work for this gun?  If not, is there any other pistol maker brands/type/specifications that I should be on the look out for the holster to work for this pistol? 

 

Any information would be greatly appreciated.
