when does a straight pull become a pump action?

[Sixshot6]

To my mind it would be a gun that would allow you to empty a case and chamber a round using a grip/'pump' without removing either your supporting hand or trigger hand from their normal shooting positions. Its quite difficult to come up with, especially considering I can think of at least one example where this isn't considered the case* in UK law.

I'd definitely agree with that sort of specification.

i always find it interesting the different methods being used by designers and importers to adhere to uk law
(and more so looking at the different mechanisms that get rejected or accepted)

Do you have an idea in mind at all for something if I may ask?

Its this rifle which I can't for the life of me remember the name as its a long collection of random letters Offensswcheizer or something



*I've seen on gun forums that at least two people claim they own this rifle in the UK (so it must be true! )

EDIT: ITs the Sommer & Ockenfuss Griffrepetierer (Whats that worth in Scrabble?!)

Fondled one of these not so long back, chambered in 30.06, it's for sale at Minsterley Ranges.

Why do I get certain images when you say you fondled a rifle?

Because you are a mucky-minded perv!

[Mattnall]

Sabre (SDI) experimented with a different type of action (not termed pump or straight-pull by them) where there was a saddle over the barrel and two 'handles' screwed in either side horizontally. These handles ran in two grooves in the float tube and an operating rod fixed in the saddle pushed on the gas key.

Holding either handle and pulling back would operate the bolt and if you cupped the float tube lightly with fingers and thumbs up either side you could operate it like a pump.

It turned out to be OK in the standing and other off-hand positions but prone it was useless as the forward hand needed to be too far forward to work. The saddle tended to jam when only operated from one side and galled on the aluminium tube. Needless to say it wasn't long before it was converted back to standard.

I'll see if I have any pictures of it, but be warned it wasn't pretty.

But you still fondled it

When does a straight pull become a pump action ?

May we state the obvious and suggest it's when you pump the action ?


Consider a straight pull action.
The firer grasps the working parts, or a lever attached thereunto, pulls it back to unchamber and eject a spent round, then releases the working parts which move forward independently of the firer, collect and feed a new round into the chamber and cock the action.

Consider a pump action
The firer pulls the working parts backwards by means of some handle connected to the aforesaid working parts, then pushes the handle forward again, driving the working parts back into battery and causing them to collect and feed a round into the chamber and cock the action. The action is pumped, id est, pulled and pushed by the direct action of the firer. The working parts are not moving freely.

Thus if someone were to design, say a fore-end grip, that connected to the working parts and drove them backwards, then disengaged and allowed the working parts to move forward independently to feed the next round, then that by strict definition is a straight pull action even if the grip is pushed forward.

You are a god amongst badgers. Do you have any ideas of how to do this right?

I bought mine Last year in .243 with sound moderator.

They are quirky to open the action on, the rfd I bought mine from couldn't figure it out and gave me discount on a 'dangerous' rifle.
