Semi-auto cycle of operation

[Erik]

I searched but couldn't find a thread addressing the cycle of operation. If there is one, duplicated for informational purposes, given the volume of newer enthusiasts:

The semi-automatic cycle of operation is thus, in order, and one must finish before the next occurs.

Basic locking breech semi-automatic cycle of operation:

1. Feeding
2. Chambering
3. Locking
4. Firing
5. Unlocking
6. Extracting
7. Ejecting
8. Cocking

They are separate and distinct, and in order. Yes, a problem originating in one can contribute to a failure in another.

Edited: Note there are others, see below.

And since there are bound to be folks who do not understand the cycle or the problems which may occur throughout it, ask away and I bet someone will come along shortly to help out.

This may tell you some of what you seek.

That list is fine for locking breech pistols....but there are a ton of blow-back non-locking pistols out there:

1. Feeding
2. Chambering
3. Firing
4. Ejecting
5. Cocking

Yup.

FMG,
That's a better than most break down of the cycle as it pertains to 1911s. Thanks.

Jackstinson, that's just what I'm hoping for, a different type of cycle of operation. Thanks.

Any others?

There are several entries in Wikipedia describing semi-auto schemes. They may not be as detailed as you want, though.

I'm not sure what the question, or statement is.

But:
There are many locking methods in common use.

*Short-recoil Browning type, as used on the majority of todays locked-breach guns.

*Blow-back, as used on .22 RF and most .32 & .380 ACP, 9mm MAK, and other low powered centerfire guns.

*Toggle-locked, as used on the P08 Luger and others.

*Gas delayed blow-back, as used on the H-K P7 series and others.

*Roller delayed blow-back, as used on the CZ52 and others.

*Gas operated rotary bolt, as used on the Desert Eagle and others.

There have been numerous other methods tried through the years, but these are the most successful, with the Browning short-recoil system leading the pack by a very wide margin.
