Now, before we get started here, this is a prototype/proof of concept. I also have no intentions of posting a video or more pictures.

So in brief, this is a pistol which has the "ram" contained within and is still slide action, I was also going to post this with a magazine which had a self contained loader as well, but it only held 4 rounds, so I deemed it unfit.

So, here is a list of it's qualities:

-Slide Action

-Self Contained

-Magazine in handle

-Magazine release in handle

-Only shoots 20ft

-Jams often

I have since disassembled this to work on future projects, hopefully I gave enough pictures to reverse engineer this if you so wish.

Step 1: Initial Disassembly

Step 2: Close Up of the Slide

Step 3: Close Up of the Ram

Step 4: Front of Slide

Step 5: This Is How the Ram Band Is Attached

Step 6: Here Is the Magazine Release

Step 7: Close Up of the Ram

Step 8: Gun Without Slide and Release

Step 9: Another Disassembly

Step 10: Close Up of the Barrel

<p>Well, I think I can see where you went wrong. In the first place, the slide was too high, there must have been too much space between the receiver and the slide. In the second place, the trigger was so close to the front of the gun that it would only give you 20 ft. max (as you have noted). Overall, this comment has been done in the worst way possible, and I apologize for that. =D</p>
<p>You're right about the space. And the trigger is indeed close. I tried moving it back though, and I found it extraordinarily difficult to get only one round to load/more not to spill out. </p><p>Originally the slide was lower for looks, but I found that without that top piece for the ram to guide it, it never shot. </p><p>I'm probably going to revisit this sometime soon and see what I can do with it.</p>
<p>Alright, sounds good. We all learn from our K'NEX &quot;fails.&quot; =D</p>
<p>If this works how I think it does, then this is really cool.</p>
<p>Another surprise innovator? I'm glad to see you're trying concepts like these. This has potential.</p>
It looks very similar to red book of westmarch's five seven v1
<p>Which itself looks similar to my TDSS... And then that was based off of another person's slide that pretty much started every pistol that looks like this. </p>
Turned out pretty good! I know any handle fed pistol is challenging!
This is pretty sweet I recently made a knex sig sauer p229 and I found it challenging to build it with it sturdy good looks and performs flawless. Squeezing a slide in with that sounds pretty rough and it still work well good job
<p>I like this I might play around with this concept</p>
<p>Just be cautious when trying to design something that extracts a round. I had a lot of difficulty with that.</p>
<p>Looks pretty bomber....! Nice build.</p>
