After the death of Selim, he was succeeded by his son Suleiman the Magnificent. During his reign, gunpowder weapons continued to be used effectively. One important example is the Battle of Mohács in 1526.

In a report given by an Ottoman general in 1602, he confessed that the army was in a distressed position due to the emphasis in European forces for musket-wielding infantry, while the Ottomans relied heavily on cavalry. Thereafter it was suggested that the janissaries, who were already trained and equipped with muskets, become more heavily involved in the imperial army while led by their agha. By the middle of the 17th century, the continued reliance of the Ottomans on over-heavy ordnance had been made out by European officers as a liability. Raimondo Montecuccoli, the Habsburg commander who defeated the Ottomans at Battle of Saint Gotthard commented on Ottoman cannon: This enormous artillery produces great damage when it hits, but it is awkward to move and it requires too much time to reload and site. Furthermore, it consumes a great amount of powder, besides cracking and breaking the wheels and the carriages and even the ramparts on which it is placed ... our artillery is more handy and more efficient and here resides our advantage over the cannon of the Turks.''
