+P+ ammo okay for Marlin Camp 9?

the camp carbines are direct blow back if i remember correctly, so i wouldn't put anything too hot in it, at least not for any quantity. If you decide to, i would suggest you buy a stronger recoil spring if one is available or at least a recoil buffer to keep your bolt from beating the sh** out of your reciever.

i think that it would heavier springs. seems like i've read about imi subgun ammo tearing one up.
I just want to make sure that I won't blow the gun up. I have a box of Gold Dot 115 +p+ that I am thinking about using for home defense. I would probably test-fire the gun with 15 rounds only. Does Wolff's sell a heavier spring? Does anyone make a conversion on the Camp 9 that will allow it to use Glock 19 magazines?
Rather than using high pressure +P+, why not load with a slower powder and go for higher velocity by taking advantage of the longer bbl and lower pressure over a longer time?
Cartridges designated +P+ will not always render higher velocities, the +P+ just indicates that the peak pressure is greater than SAAMI specs by more than ten percent.
Sam.....just thinkin out loud.

Get a 21lb. recoil spring from Wolff and you're set. I use this spring in my Camp 45 to shoot 45 Super and the 16lb. in my Camp 9 for everything. If you want to shoot the heavy stuff all the time, go with the 21lb. unit.
FWIW, 115gr. Cor-Bon JHPs went 1505fps and made 578ft/lbs in my Camp 9. For comparison, the 115gr. Cor-Bons went 1331fps in my G19.

Marlin Camp Carbine manual, page one:
"Warning: Do not use ammunition designated "+P+" in this rifle. The pressures generated by these cartridges may cause damage to the gun, or personal injury."
Personally, with heavier springs and a shock buffer to ease receiver stress, I would do it. On a stock Carbine, definitely a no-go.

Oddly, I found an old magazine article where they did some informal testing of 9mm rounds in the Carbine vs. a 4" automatic to see what velocity increases they got.
The 115 and 124 grain loads showed about 10-20% increase in speed. The 147 grain load slowed down!
Apparently, the powder runs out before the barrel does in the 16" barrel.
I would imagine that a good standard pressure 115 or 124 grain Gold Dot would be an excellent choice for this rifle.

Personally, I think that you don't have enough gun. If you're struggling to get the last OZ of power from this gun, I'd recommend you step up to something like the .45 model. Using standard pressure ammo, you'll still be getting a better defensive load than loading +P+ in this gun.
