Advantage of PPS SS vs PMI 1

What is the advantage of a SS vs a PMI 1? I realize the SS will get more shots from a 12 gram.

If the barrel (of a PMI 1) is honed and wegits installed, is the SS more accurate than a PMI 1?

Does the porting make that much of a difference (since the idea of porting to to release that C02 that travels behind the ball and since it is stockclass, I assume once you rock and cock, the C02 has left the barrel)?

About a year ago, I had a SS and had a problem with roll outs. It also had a phantom offset 15 rd feedtube that was just too long. I sold it and got a PMI 1. I kinda miss the SS, maybe it is just how it looks! Now I am debating if I should get another one.

The PMI 1 came from the factory with some easily remedied performance flaws - over spray down the barrel, a difficult to remove bolt, little or no velocity adjustment, it's slow reloading paint, and changing the 12gram is a pain.

You can pick up a working PMI around here for about $75-$100. A new Palmer SS with a vented barrel goes for $426.

If you spent that $326 difference upgrading the PMI, would it outperform the SS? For that answer, read my next point...

The accuracy of a factory PMI will be increased, but "total accuracy" will be determined by a steady hand, practise, and consistency.

I've actually shot a Palmerized PMI with a ported barrel (Thanks Chad!). While I cannot vouch for any increase of accuracy or efficiency, I can tell you that it was one of the quietest markers I ever fired. Follow this link for more info about porting-

the choice is very simple, Superstock are still being produced and Palmer's still in buisness, PMI hasn't been in production for more than 10 years now, sure you can get a PMI for 1/4 the cost if a Superstocker, but you are also buying someone's problems.

I had the same line of thinking, years ago, buying a used Sheridan and send it to Palmers for upgrade, by the time I added up the cost, it was $50 less than getting a new Superstocker, so I just bite the bullet and bought the Superstocker.

that's true that PMI is no longer in business, but there are plenty of people that can do any work needed and a lot of the work can be done by yourself.

yeah, Wunder_bread shot my Palmerized PMI-1 w/ported barrel and it is the quietest marker i own. the efficiency is better than a stock PMI-1, but there really is no noticable difference in accuracy over a stock PMI-1. i say that because i do own quite a few PMI-1s. i also see no difference in accuracy from a ported or non-ported barrel. only the noise is different between the two.

one advantage that a SS has is nickel plating. that's not a performance advantage, but certainly a durability advantage.

another advantage of the SS is the ability to strip the bolt for easier cleaning.

both of these advantages can be done to a PMI-1 but it will cost you too.

it all comes down to what you want and how much your willing to spend.

Thanks to everyone that has posted! Is a SS worth it with the current size of today's paint?

yes, the wedgit works wonders against rollouts.

I had an SS and roll outs were a problem. On my 2K Blazer I have a roll out every now and then. What type of paint do you recommend?

Yes! Yes! Yes!
I sent PPS a PMI1. The nickeled it, added a quick strp bolt, wedgits. Cost was roghly around $225, and I liked it better then my PPS SS because the SS barrel is wider then the one that comes with the PMI1. The SS suffered constant roll outs.

THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

I like sheridan soldering more than PPS jobs.

Enough to sway me one way or the other <to sheridans side>

For constant air and direct feed id take a modified pmi1 SC with a vertical feed installed.

For stock class, id take a pmi1SC

Dont like the p68 much

I own/have owned almost every configuration of Sheridan pump as well as almost every configuration of Palmer pump. The PPS pumps get more action by far (in fact I'm considering selling off most of my Sheridans).

One of the biggest differences is that the PPS guns are based on the KP valve train and not the standard Sheridan specs. That allows for a longer hammer travel, better efficiency, and a lighter pump stroke.

As has been stated, by the time you get a Sheridan "Palmerized" it will have cost you nearly as much as a scratch built PPS.

Also, PPS is now offerering smaller diameter barrels. Personally, I shoot tiny field paint (.679) with a rock forward SS and almost never have rollout problems.
